Terminal Control - Invertek Optidrive P2 series Installation & Operating Instructions Manual

5.10. Terminal Control

When delivered, the Optidrive is in the factory default state, meaning that it is set to operate in terminal control mode and all parameters have
the default values as indicated in section 6.

Connect the drive to the supply, ensuring the correct voltage and fusing / circuit breaker protection – see section 10.2.

Connect the motor to the drive, ensuring the correct star/delta connection for the voltage rating - see section 4.6.

Apply the mains power to the drive, then enter the motor data from motor nameplate; P1-07 = motor rated voltage, P1-08 = motor
rated current, P1-09 = motor rated frequency.

Connect the Drive Hardware Enable (STO) circuit as follows
o
Link Terminal 1 to Terminals 12 (STO +)
o
Link Terminal 9 to Terminal 13 (STO -)

Connect a control switch between the control terminals 1 and 2 ensuring that the contact is open (drive disabled).

Connect a potentiometer (1kΩ min to 10 kΩ max) between terminals 5 and 7, and the wiper to terminal 6.

With the potentiometer set to zero, switch on the supply to the drive. The display will show

Close the control switch, terminals 1-2. The drive is now 'enabled' and the output frequency/speed are controlled by the
potentiometer. The display shows zero speed in Hz (

Turn the potentiometer to maximum. The motor will accelerate to 50Hz, (60Hz for HP drives), the default value of P1-01, under the
control of the acceleration ramp time P1-03.

If the potentiometer is turned to minimum, the motor will decelerate to 0Hz, the default minimum speed set in P1-02, under the
control of the deceleration ramp P1-04. The output speed can be adjusted anywhere between minimum and maximum speed using
the potentiometer.

To display motor current (Amps), briefly press the

Press again to display the motor power.

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
