P1-05
Stop Mode
0
4
0
-
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
0
1
0
-
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
0
See Below
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

P1-09
Motor Rated Frequency
10
500
60 (60)
Hz
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
0
30000
0
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
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

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.

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.

3 : Output Frequency > 0.0 Hz. Logic 1 when the drive output frequency to the motor is exceeds 0.0Hz. Hysterisis is applied, defined by
P6-04.
4: Output Frequency >= Limit. Logic 1 when the motor speed exceeds the adjustable limit
5: Output Current >= Limit. Logic 1 when the motor current exceeds the adjustable limit
6: Output Torque >= Limit. Logic 1 when the motor torque exceeds the adjustable limit
7: Analog Input 2 Signal Level >= Limit. 1 Logic when the signal applied to the Analog Input 2 exceeds the adjustable limit
8 : Hoist Brake Control. When P2-18 = 8, the Optidrive is set to ‘Hoist Mode Operation’, and output relay 2 must be used to control the
motor holding brake.
9 : No Function
10 : Service Due. Logic 1 when the user settable maintenance time (P6-24) has expired. This allows the user to set a service interval
time, for example in the even where a machine requires a defiend service time interval for maintenance, the drive can provide visual
indication of the maintenance interval.
11 : Drive Ready to Run. Defined as not in inhibit mode, hardware enable present, not in mains loss condition and no trip.
12 : Drive Tripped. Logic 1 when the drive has tripped and the display shows a fault.
13 : STO Status. Logic 1 when the STO inputs are present, and the drive is not in inhibit state
Note : When using settings 4 –7, parameters P2-19 and P2-20 must be used together to control the behaviour. The output will switch
to Logic 1 when the selected signal exceeds the value programmed in P2-19, and return to Logic 0 when the signal falls below the value
programmed in P2-20.
14 : PID Error >= Limit. Logic 1 when the PID Error exceeds the adjustable threshold

P2-21 & P2-22 allow the user to program the Optidrive to display an alternative output unit scaled from an existing parameter, e.g. to
display conveyer speed in metres per second based on the output frequency. This function is disabled if P2-21 is set to 0.
If P2-21 is set >0, the variable selected in P2-22 is multiplied by the factor entered in P2-21, and can be displayed whilst the drive is
running. The display will show a ‘’ on the left hand side to indicate the customer scaled units.

Determines the time for which the drive output frequency is held at zero when stopping, before the drive output is disabled. This can
be utilised to ensure the motor has come to a complete standstill before the drive switches off, or to allow time for a holding brake to
engage. It is not intended to provide a continuous output holding torque for prolonged periods.
When operating in V/F mode, the output voltage and hence current will be dependent on the setting of P1-11.
When operating in Vector Mode, the output voltage and current are automatically controlled by the vector algorithm.
P2-24
Effective Switching Frequency
See Below
kHz
Effective power stage switching frequency. The range of settings available and factory default parameter setting depend on the drive
power and voltage rating, refer to section 2.1. Higher frequencies reduce the audible ‘ringing’ noise from the motor, and improve the
output current waveform, at the expense of increased drive heat losses.

This parameter allows an alternative deceleration ramp down time to be programmed into the Optidrive, which can be selected by
digital inputs (dependent on the setting of P1-13) or selected automatically in the case of a mains power loss if P2-38 = 2.
When set to 0.00, the drive output will be immediately disabled, and the load will coast to stop.

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.
2 : Enabled on Fault, Brown Out or Coast. As setting one, however the Spin Start function activates only following any event that may
have caused an uncontrolled stop of the motor previously.
Note
The Spin Start function cannot detect motors which are rotating at speeds above the maximum speed limit parameter (P1-01) setting
of the drive.
