Seconds

Acceleration ramp time from 0 to base speed (P-1-09) in seconds.

Note

For Optidrive P2 units Frame Sizes 2 and 3, the parameter range is adjustable between 0.00 and 600.0 seconds

For Optidrive P2 units Frame Sizes 4 and above, the parameter range is adjustable between 0.0 and 6000.0 seconds

P1-04

Deceleration Ramp Time

See Below

5.0

Seconds

Deceleration ramp time from base speed (P1-09) to standstill in seconds. When set to zero, fastest possible ramp time without trip is

activated

Note

For Optidrive P2 units Frame Sizes 2 and 3, the parameter range is adjustable between 0.00 and 600.0 seconds

For Optidrive P2 units Frame Sizes 4 and above, the parameter range is adjustable between 0.0 and 6000.0 seconds

P1-05

Stop Mode

This parameter has several functions :-

- To enable / disable the brake chopper during deceleration

- To select the stopping mode (Ramp or Coast)

- To enable the AC Flux Braking function

0 : Ramp To Stop. When the enable signal is removed, the drive will ramp to stop, with the rate controlled by P1-04 as described

above. In this mode, the drive brake transistor is disabled.

1 : Coast to Stop. When the enable signal is removed, the drive output is immediately disabled, and the motor will coast (freewheel) to

stop. If the load can continue to rotate due to inertia, and the drive may possibly be re-enabled whilst the motor is still rotating, the

spin start function (P2-26) should be enabled. In this mode, the drive brake transistor is disabled.

2 : Ramp To Stop, Brake Chopper Enabled. When the enable signal is removed, the drive will ramp to stop, with the rate controlled by

P1-04 as described above. The brake chopper is also enabled in this mode.

3 : Coast to Stop, Brake Chopper Enabled. When the enable signal is removed, the drive output is immediately disabled, and the

motor will coast (freewheel) to stop. If the load can continue to rotate due to inertia, and the drive may possibly be re-enabled whilst

the motor is still rotating, the spin start function (P2-26) should be enabled. The drive brake chopper is enabled in this mode, however

it will only activate when required during a change in the drive frequency setpoint, and will not activate when stopping.

4 : AC Flux Braking. AC Flux braking provides improved braking torque during stopping and dceceleration. In this mode, the brake

chopper is disabled, however braking torque is improved.

P1-06

Energy Optimiser

Only active when enhanced V/F motor control mode is selected (P4-01 = 2).

0 : Disabled

1 : Enabled. When enabled, the Energy Optimiser attempts to reduce the overall energy consumed by the drive and motor when

operating at constant speeds and light loads. The output voltage applied to the motor is reduced. The Energy Optimiser is intended for

applications where the drive may operate for some periods of time with constant speed and light motor load, whether constant or

variable torque.

P1-07

Motor Rated Voltage

See Below

Volts

This parameter should be set to the rated (nameplate) voltage of the motor (Volts)

The factory default setting of this parameter is drive model dependent as follows :-

All kw & HP models intended for 200 –240 volt operation (e.g. ODP-2-x2xxx-xxF4x) : Factory setting = 230 Volts, Maximum 250 Volts

All kW models intended for 380 –480 volt operation (e.g. ODP-2-x4xxx-3KFxN) : Factory setting = 400 Volts, Maximum 500 Volts

All HP models intended for 380 –480 volt operation (e.g. ODP-2-x4xxx-3HFxN) : Factory setting = 460 Volts, Maximum 500 Volts

When this parameter is set to the motor nameplate voltage, the output voltage from the drive is controlled automatically and

maintained at the correct level wherever possible regardless of variations in supply voltage or DC Bus Voltage.

When P1-07 = 0, the voltage compensation function of the inverter is disabled. The output voltage applied to the motor will increase

or decrease with changes in the DC Bus voltage.

Note

The RMS output voltage from the inverter can never exceed the incoming supply voltage.

P1-08

Motor Rated Current

See Below

Amps

This parameter should be set to the rated (nameplate) current of the motor.

The factory default setting of this parameter is the set to the maximum continuously available output current of the drive

Optidrive P2 Advanced User Guide Rev 2.00

www.invertekdrives.com

Optidrive P2 Parameter Set Overview

P1-09

Motor Rated Frequency

500

60 (60)

This parameter should be set to the rated (nameplate) frequency of the motor.

The factory default setting of this parameter is drive model dependent as follows :-

All kW models (e.g. ODP-2-xxxxx-xKFxx) : Factory setting = 50Hz

All HP models (e.g. ODP-2-xxxxx-xHFxx) : Factory setting = 60 Hz

P1-10

Motor Rated Speed

30000

Rpm

This parameter can optionally be set to the rated (nameplate) rpm of the motor. When set to the default value of zero, all speed

related parameters are displayed in Hz, and the slip compensation for the motor is disabled. Entering the value from the motor

nameplate enables the slip compensation function, and the Optidrive display will now show motor speed in estimated rpm. All speed

related parameters, such as Minimum and Maximum Speed, Preset Speeds etc. will also be displayed in Rpm.

Note

When the drive is operated with the optional Encoder Feedback Interface, this parameter must be set to the correct nameplate Rpm of

the connected motor.

P1-11

V/F Mode Voltage Boost

0.0

See Below

This parameter is effective only when operating in V/F Mode (P4-01 = 2).

Voltage boost is used to increase the applied motor voltage at low output frequencies, in order to improve low speed and starting

torque. Excessive voltage boost levels may result in increased motor current and temperature, and force ventilation of the motor may

be required.

An automatic setting () is also possible, whereby the Optidrive will automatically adjust this parameter based on the motor

parameters measured during an autotune.

The factory default and maximum limit for this parameter are drive model dependent, refer to section 0 for further information

P1-12

Primary Command Source Mode

0 : Terminal Control. The drive responds directly to signals applied to the control terminals.

1 : Uni-directional Keypad Control 1)2)3) The drive can be controlled in the forward direction only using an external or remote Keypad

2 : Bi-directional Keypad Control 4) The drive can be controlled in the forward and reverse directions using an external or remote

Keypad. Pressing the keypad START button toggles between forward and reverse.

3 : PID Control. The output frequency is controlled by the internal PID controller.

4 : Fieldbus Control. Control via Modbus RTU if no fieldbus interface option is present, otherwise control is from the fieldbus option

module interface

5 : Slave Mode. The drive acts as a Slave to a connected Optidrive operating in Master Mode

6 : CAN bus Control. Control via CAN bus connected to the RJ45 serial interface connector

Note

1) When operating with P1-12 = 1 or 2, the drive will not operate the motor unless the enable signal is present (e.g. Control

Terminals 1 & 2 are linked together), regardless of the setting of P2-37. If P2-37 > = 4, the drive will start when the link is

closed between terminals 1 & 2, and will not require the keypad start button to be pressed. If P2-37 < 4, the Start Button

must be pressed to operate the drive after the link is closed between terminals 1 & 2.

2) The motor direction of rotation may still be controlled by signals applied to the digital inputs, dependent on the setting of

P1-13, e.g. the motor can still be controlled in both forward and reverse directions if required, however the Reverse direction

function of the Start key is disabled.

3) When operating in this mode and utilising a setting of P1-13 that allows preset speeds to be also selected from the drive

digital inputs, setting a negative value in the preset speed parameter will cause the drive to reverse the direction of motor

rotation.

4) When P1-12 = 2, the direction of motor rotation may be changed by any of the following :-

a. Pressing the keypad Start button

b. A Reverse Digital Input, dependent on the setting of P1-13

c. Selecting a Negative Preset Speed

It is important to ensure that a combination of the above used incorrectly does not result in unexpected operation.

P1-13

Digital Inputs Function Select

Defines the function of the digital inputs depending on the control mode setting in

P1-12. See section 1.7 on page 30 for further information.

The Skip Frequency function is used to avoid the Optidrive operating at a certain output frequency, for example at a frequency which

causes mechanical resonance in a particular machine. Parameter P2-09 defines the centre point of the skip frequency band, and is

used conjunction with P2-10. The Optidrive output frequency will ramp through the defined band at the rates set by the acceleration

and deceleration ramps currently in use, and will not hold any output frequency within the defined band. If the frequency reference

applied to the drive is within the band, the Optidrive output frequency will remain at the upper or lower limit of the band.

Spin Start Enable

0 : Disabled

1 : Enabled. When enabled, on start up the drive will attempt to determine if the motor is already rotating, and will begin to control

the motor from its current speed. This can be useful for high inertia loads, or fans which may spin due to air movement even when the

drive is not enabled. A short delay may be observed when starting motors which are not already rotating. The spin start will detect the

motor direction of rotation, and will automatically operate and control the motor from that point, including reversing the direction of

motor rotation where required.

 : Following a Power On or Reset, the drive will automatically start if Digital Input 1 is closed before power on.

The drive must be powered down or reset manually to reset the counter. The numbers of restart attempts are counted, and if the

drive fails to start on the final attempt, the drive will fault with, and will require the user to manually reset the fault.

P2-37

Keypad / Fieldbus Starting Control

This parameter controls the starting behaviour of the drive when operating in Keypad Mode or Fieldbus Mode (selected by P1-12).

Settings 0 to 3 are active in Keypad Mode only (P1-12 = 1 or 2), and define the speed at which the drive will initially operate following

the pressing of the keypad Start button.

0 : Minimum Speed, Keypad Start. Following a stop and restart, the drive will always initially run at the minimum speed set in P1-02.

This applies even if the drive is re-enabled whilst still decelerating the motor from the previous stop command.

1 : Previous Operating Speed, Keypad Start. Following a stop and restart, the drive will return to the last keypad setpoint speed used

prior to stopping.

2 : Current Running Speed. Where the Optidrive is configured for multiple speed references, when switched to keypad mode by a

digital input, the drive will continue to operate at the last operating speed. This setting can be used for ‘Bumpless’ changeover

between automatic and manual operating modes of the drive, e.g. typically Hand / Auto control or Local / Remote control.

3 : Preset Speed 8, Keypad Start. Following a stop and restart, the Optidrive will always initially run at Preset Speed 8 (P2-08)

4 : Minimum Speed, Terminal Start. Following a stop and restart, the drive will always initially run at the minimum speed P1-02. The

drive starting is controlled from the digital inputs, based on the setting of P1-13.

5 : Previous Operating Speed, Terminal Start. Following a stop and restart, the drive will return to the last keypad setpoint speed used

prior to stopping. The drive starting is controlled from the digital inputs, based on the setting of P1-13.

6 : Current Running Speed, Terminal Start. Where the Optidrive is configured for multiple speed references (typically Hand / Auto

control or Local / Remote control), when switched to keypad mode by a digital input, the drive will continue to operate at the last

operating speed. The drive starting is controlled from the digital inputs, based on the setting of P1-13.

7 : Preset Speed 8, Terminal Start. Following a stop and restart, the Optidrive will always initially run at Preset Speed 8 (P2-08). The

drive starting is controlled from the digital inputs, based on the setting of P1-13.

P2-38

Mains Loss Ride Through / Stop Control

Controls the behaviour of the drive in response to a loss of mains power supply whilst the drive is enabled.

0 : Mains Loss Ride Through. The Optidrive will attempt to continue operating by recovering energy from the motor and connected

load. Providing that the mains loss period is short (e.g. a ‘Brown Out’), the drive enable control remains applied and that sufficient

energy can be recovered before the drive control electronics power off, the drive will automatically maintain motor operation (with

reduced output speed depending on the load), and recover back to the normal operating point on return of mains power.

Where the mains power supply is lost for a longer period (e.g. a ‘Black Out’) and there is insufficient kinetic energy available from the

load to maintain the drive electronic power supply, the restarting behaviour of the drive on return of the power supply will be

controlled by P2-36.

1 : Coast To Stop. On a loss of mains power supply, either ‘Brown Out’ or ‘Black Out’, the Optidrive will immediately disable the output

to the motor, allowing the load to coast or free wheel. When using this setting with high inertia loads, which may still be rotating when

the mains power returns, the Spin Start function (P2-26) should be enabled.

2 : Fast Ramp To Stop. On a loss of mains power supply, either ‘Brown Out’ or ‘Black Out’, the Optidrive will attempt to decelerate the

load to standstill at the rate programmed in the Fast deceleration time (P2-25), by recovering energy from the load. As the speed of

the load approaches zero, if the mains power supply has not been restored, the drive control electronics may power down shortly

before the load reaches a complete standstill. If the power returns whilst the drive is still decelerating the load, and the run signal is

maintained, the drive will resume operation and accelerate the load back to the operating speed.

3 : DC Power Supply. This option should be used where the drive is powered via the DC Bus terminals only, and no AC supply is

present.

the internal ramp times of the drive are disabled. Where a greater PID error exists, the ramp times are enabled to limit the rate of

change of motor speed on large PID errors, and react quickly to small errors.

Setting to 0.0 means that the drive ramps are always enabled. This parameter is intended to allow the user to disable the drive internal

ramps where a fast reaction to the PID control is required, however by only disabling the ramps when a small PID error exists, the risk

of possible over current or over voltage trips being generated are reduced.

0 : IM Motor Vector Speed Control with Torque Limit. Suitable for use with AC induction motors, Vector Speed Control Mode provides

greater low speed torque, and improved motor speed regulation with respect to load changes. The drive primarily operates in Speed

Control Mode, where the motor speed is controlled by the chosen setpoint source. When the output torque level approaches the

maximum limit, the drive will reduce the motor speed in attempt to reduce the torque demand required. The factory parameter

settings allow a fixed maximum torque limit of 200% set in parameter P4-07. Alternative torque limit settings and variable torque

limits may be selected using P4-06 and P4-07.

1 : IM Motor Vector Torque Control with Speed Limit. Suitable for use with AC induction motors, when Vector Torque Control Mode is

selected, the drive primarily operates in Torque Control Mode, where the motor attempt to generate the output torque level required

by the torque setpoint source. This will generally cause the motor to accelerate in speed. When the output speed approaches the

maximum limit, the drive will not accelerate beyond this point. The speed limit source should be selected by using P1-12 and P1-13,

and the torque reference source should be set in P4-06.

Note

Options 3 to 6 are only available when Advanced Parameter Access has been set.

P4-02

Motor Parameter Auto-tune Enable

When set to 1, the drive immediately carries out an autotune to measure the motor parameters for optimum control and efficiency.

Following completion of the autotune, the parameter automatically returns to 0.

Note

All motor nameplate data should be programmed into the drive, e.g. P1-07, P1-08, P1-09 and P4-05 prior to starting the autotune

Whilst the autotune does not require the motor to rotate, it may still cause some movement of the motor shaft,

thereby it is important to ensure that the motor and load are safe to operate prior to starting the autotune.

The autotune does not require the load to be removed from the motor, however the motor brake should be

released providing it is safe to do so.

P4-03

Vector Speed Controller Proportional Gain

0.1

400.0

50.0

Sets the proportional gain value for the speed controller when operating in Vector Speed or Vector Torque motor control modes (P4-

01 = 0 or 1). Higher values provide better output frequency regulation and response. Too high a value can cause the speed to

overshoot the setpoint during acceleration, and may also cause speed instability and possibly over current trips. For applications

requiring best possible performance, the value should be adjusted to suit the connected load by gradually increasing the value and

monitoring the actual output speed of the load until the required dynamic behaviour is achieved with little or no overshoot of the

target speed during acceleration and deceleration.

In general, higher friction loads can tolerate higher values of proportional gain, and high inertia, low friction loads may require the gain

to be reduced.

P4-04

2 : Analog Input 2. The output torque is controlled based on the signal applied to Analog Input 2, whereby 100% input signal level will

result in the drive output torque being limited by the value set in P4-07.

3 : Fieldbus. The output torque is controlled based on the signal from the communications Fieldbus, whereby 100% input signal level

will result in the motor output torque being set or limited to motor rated torque.

4 : Master. The output torque is controlled based on the signal from the Master when operating in Master / Slave mode.

0 : Disabled. The present value of the motor overload accumulator is not stored during power off.

1 : Enabled. The value of the motor thermal overload accumulator is stored during power off.

Whilst the motor is being operated, the drive continuously monitors the output current over a time period, to determine the likely

operating temperature of the motor. If the motor operates at high current for a period of time, the drive may trip to protect the motor

and prevent damage. When this function is disabled (default setting), removing the power supply from the drive will result in the

thermal overload value for the motor being reset to zero, hence the motor could potentially be operated and damaged. By enabling

this parameter, even if the mains power is removed from the drive, the value is retained, and reused at the next power on, in order to

avoid the risk of damage to the motor.

P6-01

Enable Firmware Upgrade

Enables the firmware upgrade mode, allowing the User Interface firmware and/or the Power Stage Control firmware to be upgraded.

Options are:

0 : Disabled

1 : Upgrade User Interface and Power Stage Control firmware

2 : Upgrade User Interface firmware only

3 : Upgrade Power Stage Control firmware only

NOTE

This parameter should not be adjusted by the User. The firmware upgrade process is carried out fully automatically using Optitools

Studio PC software.

P6-02

Automatic Thermal Management Minimum Switching

Frequency

Model

Dependent

kHz

This parameter defines the minimum effective switching frequency which the drive will use.

During operation, the drive measures the power module temperature and will switch automatically to a lower switching frequency if

the temperature reaches a pre-defined limit. This parameter determines the lowest frequency that can be used. In the event that the

power module temperature continues to increase, the drive will trip on over temperature.

P6-03

Auto Reset Time Delay

Sets the delay time which will elapse between consecutive drive reset attempts when Auto Reset is enabled in P2-36

P6-04

Relay Output Hysteresis Control

0.0

25.0

0.3

This parameter works in conjunction with P2-11 and P2-13 = 2 or 3 to set a band around the target speed (P2-11 = 2) or zero speed

(P2-11 = 3). When the speed is within this band, the drive is considered to be at target speed or Zero speed. This function is used to

prevent “chatter” on the relay output if the operating speed coincides with the level at which the digital / relay output changes state.

e.g. if P2-13 = 3, P1-01 = 50Hz and P6-04 = 5%, the relay contacts close above 2.5Hz

P6-05

Encoder Speed Feedback Enable

0 : Disabled

1 : Enabled. Setting to 1 enables encoder control mode of operation, which requires an optional encoder feedback interface. For

correct operation, ensure that the encoder has been properly fitted to the motor and its wiring is connected to the encoder feedback

module in accordance with the Encoder Feedback Interface User Guide. Before enabling this parameter, ensure that the sense of

rotation is correct by using parameter P0-57 (encoder feedback speed) while running in V/f mode. The sign in P0-57 should match that

of the speed reference.

P6-06

Encoder PPR

65535

When using the optional encoder feedback interface (OPT-2-ENCOD), this parameter should be set to the number of Pulses Per

Revolution for the connected encoder. This value has to be set correctly to guarantee proper operation of the drive when Encoder

feedback mode is enabled (P6-05 = 1). Improper setting of this parameter could cause the loss of control of the drive and / or a trip. If

set to zero, encoder feedback will be disabled.

P6-07

Speed Error Trip Level

0.0

100.0

5.0

When operating in vector mode, this parameter defines the maximum permissible error between the commanded motor speed and

the esitamed or measured motor speed. This provides protection against overspeeding or loss of motor control. If the speed error

exceeds this limit, the drive will trip. When set to zero, this protection is disabled.

P6-08

Maximum Speed Reference Frequency

kHz

When the motor speed reference is to be controlled by a frequency input signal (connected to Digital input 3), this parameter is used

to define the input frequency which corresponds to the maximum motor speed (set in P1-01). This maximum frequency that can be

set in this parameter must be in the range 5kHz to 20kHz.

When set to 0, this function is disabled.

P6-09

Speed Droop Control

0.0

25.0

0.0

This parameter only applies when the drive is in vector speed control mode. (P4-01=0, 3, 4,5, 6) When set to zero, the speed droop

control function is disabled. If P6-09 > 0, this parameter effectively defines a slip speed at motor rated output torque.

The droop speed is the percentage value of P1-09. Depending on the motor load condition, the reference speed will be reduced by a

certain droop value before goes into speed controller, calculated as shown below:

Droop speed = P6-09 * P1-09

Droop value = Droop speed * ( Motor real torque / Motor rated torque)

Speed controller input = Speed reference –Droop value

Droop control can be used to provide a small reduction in motor speed in proportion to the applied load. This can be especially useful

where multiple motors drive a common load, and the load should be shared evenly between the motors.

The real time droop value may be viewed in P0-62.

P6-10

Enable Function Block Program Operation

0 : Function Block Program Disabled.

1 : Function Block Prgram Enabled. This parameter must be set to 1 to enable any Function Block Program loaded into the drive to

operate. When set to 0, the Function Block Program will be disabled.

P6-11

Speed Holding Time on Enable

250

Defines a time period for which the drive will run at Preset Speed 7 (P2-07) when the Enable signal is applied to the drive. The preset

speed can be any value from minimum to maximum frequency and in either direction. This function can be useful in applications

requiring controlled start-up behaviour regardless of the normal system operation, and allows the user to program the drive to always

start at the same frequency, with the same direction of rotation for a specified time period before returning to normal operation.

Speed Holding / DC Injection Time on Disable

250

When P6-18 = 0, defines a time period for which the drive will run at Preset Speed 8 (P2-08) following removal of the Enable signal,

before ramping to stop.

Note

Setting this parameter > 0 will result in the drive continuing to operate for the set time at the preset speed after the enable signal has

been removed. It is important to ensure this method of operation is safe prior to using this function.

When P6-18 > 0 and Hoist Mode is not enabled (P2-18 ≠ 8), a DC Current, which may be adjusted using P6-18 is injected into the motor

for the time set by this parameter when stopping, which can be useful to ensure the motor has completely stopped.

P6-13

Hoist Mode : Brake Release Time

0.0

Sets the time for which the drive will hold at the Brake Release Speed (set in P2-07 - Preset Speed 7) to allow the motor brake to

release.

P6-14

Hoist Mode : Brake Apply Time

0.0

5.0

0.3 –0.5

Sets the time for which the drive will hold at the Brake Apply Speed (set in P2-08 - Preset Speed 8) to allow the motor brake to engage.

For vertical hoist applications this value should not be set below the time required for the brake to engage (brake response time, as

specified by the brake manufacturer). The minimum time is 0.1s.

P6-15

Hoist Mode : Brake Release Torque Threshold (Torque

Prove)

0.0

200.0

8.0

Sets the torque level, as a % of the nominal motor torque, which must be generated prior to the drive Output Relay 2 closing to signal

the motor holding brake to release. This is used to ensure the motor is connected and that sufficient torque has been generated to

prevent the load dropping on release of the mechanical brake. The torque threshold function is not active in V/f mode.

P6-16

Hoist Mode : Torque Threshold Timeout

0.0

25.0

5.0

Sets the time for which, following a start command, the drive will attempt to apply enough torque to the motor to reach the hoist

Sets the brake resistor power in kW, with a resolution of 0.1kW. This value is used for the brake resistor thermal protection.

The thermal protection allows 10 x P6-20 for 5 seconds within a 50 second period, or 50 x P6-20 for 1 second within 50s.

P6-21

Brake Chopper under Temperature Duty Cycle

0.0

20.0

2.0

This parameter defines the duty cycle applied to the brake chopper whilst the drive is in an under temperature trip state. A brake

resistor can be mounted to the drive heat sink, and used to maintain the drive temperature above the minimum operating

temperature. This parameter should be used with extreme care, as incorrect adjustment may result in exceeding the rated power

capacity of the resistor. External thermal protection for the resistor should always be used to avoid this risk.

P6-22

Cooling Fan Runtime Counter Reset

1.3.7. Parameter Group 7 –Motor Data

experienced users who fully understand the functions of the parameters.

P7-01

Motor Stator Resistance (Rs)

Ohms

Motor stator resistance value measured during the autotune.

P7-02

Motor Rotor Resistance (Rr)

Ohms

For induction motors: phase to phase rotor resistance value in ohms.

P7-03

Motor Stator Inductance (Lsd)

For induction motors: phase stator inductance value.

For permanent magnet motors: phase d-axis stator inductance in Henry (H).

P7-04

Motor Magnetising Current (Id rms)

0.0

For induction motors: magnetizing / no load current. Before Auto-tune, this value is approximated to 60% of motor rated current (P1-

08), assuming a motor power factor of 0.8.

P7-05

Motor Leakage Coefficient (Sigma)

For induction motors: motor leakage inductance coefficient

P7-06

Motor Stator Inductance : PM Motors (Lsq)

For permanent magnet motors: phase d-axis stator inductance in Henry (H).

P7-07

Enhanced Generator Mode

Valid in vector control mode only, provides improved performance and control of the motor when operating in regenerative mode at

low speed.

P7-08

Motor Parameter Adaptation Enable

0 : Disabled

1 : Enabled. For Induction motors only and effective in vector control mode (P4-01 = 0 or 1), allows the stator resistance to be adapted

during normal operation to compensate for increase in the moror temperature.

P7-09

Over Voltage Current Limit

0.0

100.0

5.0

Effective in vector speed control mode only, and will come into function once the drive DC bus voltage increases above a preset limit.

This voltage limit is set internally just below the over voltage trip level. This parameter will effectively limit the output torque current

in order to prevent a large current flowing back to the drive, which may cause an Over-voltage trip. A small value in this parameter will

limit the motor control torque when the drive DC bus voltage exceeds the preset limit. A higher value may cause a significant

distortion in the motor current, which may cause an aggressive, rough motor behaviour.

P7-10

System Inertia Constant

600

System Load Inertia to Motor Inertia Ratio entered as H = (JTot / JMot). This value can normally be left at the default value (10) and is

used by the drive control algorithms as a feed-forward control variable to provide optimum torque current to accelerate the load.

Hence accurate setting of the inertia ratio will produce a better system response and dynamic behaviour.

P7-11

Pulse Width Minimum Limit

500

This parameter is used to limit the minimum output pulse width, which can be used for long motor cable applications. Increasing the

value of this parameter will reduce the risk of over-current trips, but will also reduce the maximum available output motor voltage.

P7-12

V/F Mode / PM Mode Magnetising Period

5000

Defines the delay time between the output stage enabling at 0.0Hz prior to the output frequency beginning to ramp to accelerate the

motor. In V/F mode, this allows time for the motor to correctly magnetise, and avoids possible over current trips that may occur if the

output frequency begins to ramp before the motor flux has stabilised.

In IM vector mode, this function is automatically handled through the vector control algorithm.

In PM and BLDC modes, this time is again used, and provides the same function, allowing alignment of the rotor flux prior to

accelerating the motor, and again can help avoid over current trips.

P7-13

Vector Speed Control Derivative Gain

0.0

400.0

0.0

Sets the differential gain (%) for the speed controller in vector mode operation.

P7-14

Low Frequency Torque Boost

0.0

100.0

0.0

Effective in all motor control modes, except V/F mode (P4-01 = 2), but primarily intended for use with synchronous motors.

Allows a boost current to be applied at start-up and low frequency (limit defined by P7-15), as a percentage of the motor rated current

(P1-08). Injecting some additional current into the motor at low speed helps to ensure that the rotor alignment is maintained,

imrpoving operation of the motor at lower speeds.

In order to determine the correct setting, run the drive at the lowest frequency required by the application and increase boost levels

to provide both required torque and smooth operation whilst avoiding excessive current levels which may cause nuisance tripping.

P7-15

Torque Boost Frequency Limit

0.0

50.0

0.0

Frequency range for applied boost current (P7-14) as a % of motor rated frequency (P1-09). This sets the frequency cut-off point above

which boost current is no longer applied to the motor.

PM Motor Signal Injection Enable

Enables signal injection for use with PM motors. A high frequency signal is injected into the motor at a level defined by P7-17. The

information derived from this signal is then used to determine the motor speed more accurately when operating at low or zero speed,

improving operation without the need for a feedback encoder.

0: Disabled

1: Enabled During Magnetizing Period

2: Enabled During Low Speed Operation

3: Enabled During Magnetizing Period and Low Speed Operation

P7-17

PM Motor Signal Injection Level

0.0

100

Sets the signal level used during the signal injection function in P7-17. If the value is too high, the drive may trip with over current.

P7-18

Over Modulation Enable

0: Disabled

1 : Enabled. When enabled, over modulation provides a small increase in the available output voltage from the drive, which can assist

in applications where the supply voltage is too low to provide the required motor voltage, resulting in an increased motor current.
