Connect drive according to diagram below, ensuring that motor terminal box connections are correct (see diagram,
right). Refer to the ELECTRICAL DATA overleaf for the sizes of cabling and wiring.
It is recommended that the power cabling should be PVC-insulated shielded cable, laid in accordance with local
industrial regulations and codes of practice.
* If fitted, a filter should be physically close to the Drive. For maximum effectiveness, the metal case of the filter and
the heat sink of the drive should be electrically connected, i.e., screw both to a metal backplate and ensure metal-to-
metal contact
Refer to the Digital Inputs table for details of the digital input functions 1 to 3
If shielded cabling is used for the control wiring, connect the cable screen to 0V of drive, terminals 1, 7 or 9
GROUNDING (EARTHING)
The ground terminal of each Optidrive1ph should be individually connected DIRECTLY to the site earth (ground)
busbar (through the filter if installed) as shown. Optidrive1ph ground connections should not loop from one drive to
another, or to, or from any other equipment. Ground loop impedance must conform to local industrial safety
regulations. To meet UL regulations, UL approved ring crimp terminals should be used for all earth wiring
connections.
OPERATION – BASICS + GETTING STARTED
WARNING
§The STOP function does not remove potentially lethal high voltages. ISOLATE the drive and wait 10 minutes
before starting any work on it
§If it is desired to operate the drive at any frequency/speed above the rated speed (P-09/ P-10) of the motor, consult
the manufacturers of the motor and the driven machine about suitability for over-speed operation

PSC MOTOR WIRING
EASY START-UP
When delivered, the Optidrive1ph is in the default state, meaning that it is set to operate in terminal mode and all
parameters (P-xx) have the default values as shown overleaf.
§Connect a control switch between the control terminals 1 and 2.
§Connect a potentiometer (500 Ωmin to 10 kΩmax) between terminals 5 and 7, and wiper to terminal 6.
§Set the control switch between pins 1 and 2 open so that the drive is ‘disabled’.
§With the potentiometer set to zero, switch on the supply to the drive. The display will show StoP.
§Close the control switch, terminals 1-2. The drive is now ‘enabled’ and the output frequency/speed will ramp up to
50hz immediately for time determined in P-32 (2-sec) before ramping back down to the minimum speed set in P-
02 (10.0Hz). The speed of the motor can now be controlled by the potentiometer. Turn the potentiometer to
maximum. The motor will accelerate to 50Hz (the default value of P-01) under the control of the accelerating ramp
time P-03. The display shows H 50.0 (50Hz) at max speed.
§To display motor current (A), briefly press the Navigate key ⇔.
§Press ⇔again to return to speed display.
§To stop the motor disable the drive by opening the control switch (terminals 1-2).
If the enable/disable switch is opened the drive will decelerate to stop at which time the display will show StoP. If the
potentiometer is turned to zero with P-02 set to 0.0Hz and the enable/disable is closed the display will show 0.0Hz, if
left like this for 20 seconds the drive will go into standby mode, display shows Stndby, waiting for a speed reference.
SIMPLE PARAMETER ADJUSTMENTS
The factory-set default parameter values may give satisfactory performance, however certain adjustments may be
beneficial.
Maximum and Minimum Speeds P-01 & P-02
Set P-01 to the maximum speed and P-02 to the minimum speed for your application. These limits are mirrored for
negative speeds. If a non-zero minimum speed is set in P-02, the motor will ramp (P-03) to this minimum speed as
soon as the drive is enabled.
Acceleration and Deceleration P-03 & P04
Ramps which are too short will cause the drive to deliver currents in excess of full load current and may result in it
tripping out or the motor stalling
Stop Mode P-05
Select method of stopping required when drive is disabled. Ramp to stop (P-05 = 0) decelerates the motor at the rate
set by deceleration ramp time P-04. Freewheel/ Coast to stop (P-05=1) disables the drive output immediately,
allowing the motor to decelerate naturally due to friction or under the control of a mechanical brake
V/F Characteristic P-06
Certain loads such as fans and centrifugal pumps need less torque at low speed. Set P-06=1 to a higher value to
reduce power loss at low speeds for this load type. ‘0’ creates max torque.
Rated Current, Rated Frequency and Rated Speed P-08, P-09, P-10.
Parameters P-08 and P-09 should to be set to correspond with the rated current and frequency shown on the motor
rating plate.

Bardac
drives
page 7
Parameter P-10 is optional. If this parameter is set to zero (default state), speed will be displayed in Hz; if speed
indication is required in rpm, enter the motor rated speed (speed at full load) from the motor rating plate. This also
activates the slip compensation feature which improves speed regulation (holding) for varying load conditions.
Voltage Boost P-11
Any load which is ‘sticky’ to start will benefit from a voltage boost on starting. P-11 permits a boost of up to 25% of full
motor voltage to be applied.
NOTE: Use of this parameter increases motor heating at low speeds
Terminal or Keypad Control P-12
Terminal control (P-12=0) is used when the drive needs to be controlled from some remote point, such as a control
panel interface or machine system.
Keypad control (P12=1 or 2) is used for local, manual control and commissioning
Extended Parameter Set P15 to P-40 and P-00
The Extended Parameter Set is intended for use by specialist drives engineers and technicians and will not generally
be required for simple applications.
OPERATION – USING THE KEYPAD
MANAGING THE KEYPAD
When the drive is delivered from the factory, only the Standard Parameter Set (see overleaf) is accessible.
To access the Standard Parameter Set,press the Navigate key for >1 sec.
•Scroll through P-01 to P-14 (and roll over to P-01) by pressing sor t
•To display the parameter value, press
•To edit the parameter value, press sor t
•To return to the parameter number, press
•To store a value and / or exit from edit mode, press for >1 sec or press no button for >20 sec.
•To access the Extended Parameter Set, set P-14 = 101 and press
NOTE To restrict unauthorized access, make P-37 = any value from 0 to 9999.
•When in the Extended Parameter Set (except P-00), the display will revert to normal if no button is pressed for >20
sec.
•When P-00 is accessed, the display will revert to normal if no button is pressed for >60 sec.
TO SAVE CHANGES to Parameter settings, switch the power supply off and wait for the drive to power down
(screen blank) before switching on.
NOTE that this assumes P-38 = 0 (default). If P-38 = 1, changes are not saved.
TO RESTORE ALL DEFAULT VALUES, stop the drive and when display shows StoP, press and hold the s, t
and STOP keys simultaneously for 1 second. The display will show P-dEF. Access code P-37 will revert to 101 but
the hours-run meter P-39 is not affected. Press STOP to resume normal operation.

may be made but these will not be stored when the Optidrive1ph powers down.
When P-38 = 2, parameters are locked and cannot be changed thus preventing
unauthorised access.

TROUBLESHOOTING
TO CLEAR A TRIP CONDITION Remove the condition which caused the trip and press the STOP key or re-
enable the drive. The drive will restart according to the mode selected by P-30.
If the motor is stopped and the display shows STOP, there is no fault; the drive output is disabled and the drive is
ready to run.
Fault
Code What has happened What to do
P-deF Default parameters loaded Press STOP key, drive is ready to configure for particular application
O-I Over current on drive output.
Excess load on the motor.
Motor at constant speed: investigate overload or malfunction. Motor
starting: load stalled or jammed. Check for motor wiring error.
Motor accelerating/decelerating: The accel/decel time too short
requiring too much power. If not possible to increase P-03 or P-04, a
bigger drive will be required
O-Uolt Over voltage on DC bus Over voltage. Check that supply voltage is within drive limits. Increase
decel ramp time P-04. If a brake resistor is used, check that P-34 = 1
or 2.
U-Uolt Under voltage on DC bus This occurs routinely when power is switched off. If it occurs during
running, check power supply voltage.
OI-b Brake resistor short circuit Check resistor cabling, if ok, check the brake resistor is not short
circuit
I.t-trP The drive has tripped on overload
after delivering greater than 100%
load for a period of time.
Check to see when the decimal points are flashing (drive in overload)
and either decrease acceleration rate or load. Check cable length is
within specification. Try increasing the value of the voltage applied to
the motor ie reduce the value of P-06.
th-Flt Faulty thermistor on heatsink. Refer to your Bardac Authorized Distributor.
E-triP External trip (on dig. input 2 or 3)
External trip activated via digital input 2 when P-19=3. If used for
motor thermistor, check motor temperature; the motor may need to be
forced cooled particularly if running continuously at low speed and high
torque.
EE-F EEPROM fault. Parameters not
saved, defaults reloaded. Try again. If problem recurs, refer to your Bardac Authorized Distributor.
PS-Trp Internal power stage fault Check wiring to motor, look for ph-ph or ph-Earth short circuit. Check drive ambient temp, additional space or cooling needed?
Check drive is not forced into overload.
O-t Heatsink over temperature Check drive ambient temp. Additional space or cooling needed?
Iin-F Current analog input out of range Analog input format of 4..20mA selected and input current value
<2mA. If P-19=0, check the operation of digital input 3.
OL-br Braking Resistor Overload Increase decel. time, P-04 or reduce braking resistor value
SC-trP Serial communications trip
Check OptiLink integrity between drives connected optically or
electrically via RS485, check drives in a network have different
addresses, P-36. If the OptiPort is used, check that the drive address
of the OptiPort (P-36) matches that of the Optidrive. If multiple
Optidrives are used in a network check that each drive has a unique
address.

Voltage / Frequency (V/f) Characteristic
The V/f characteristic is defined by parameter P-06 as shown. Increasing the value of P-06 decreases the volts applied to the
motor at a given frequency; reducing the voltage reduces the amount of current flowing in the motor hence the torque at the
motor shaft. This feature is used to save energy in applications where the torque required at low speeds is less than at higher
speeds. A particular value of P-06 should be determined by trial and error.
