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

5.11. Keypad Control

To allow the Optidrive to be controlled from the keypad in a forward direction only, set P1-12 =1:

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).

5.12. Operating in Sensorless Vector Speed Control Mode
Optidrive P2 can be programmed by the user to operate in Sensorless Vector mode, which provides enhanced low speed torque, optimum
motor speed regulation regardless of load and accurate control of the motor torque. In most applications, the default Voltage Vector control
mode will provide adequate performance, however if Sensorless Vector operation is required, use the following procedure.

Ensure advanced parameter access is enabled by setting P1-14 = 101

Enter the motor nameplate details into the relevant parameters as follows
o
P1-07 Motor Rated Voltage
o
P1-08 Motor Rated Current
o
P1-09 Motor Rated Frequency
o
(Optional) P1-10 Motor Rated Speed (Rpm)
o
P4-05 Motor Power Factor

Select Sensorless Vector control mode by setting P4-01 = 0

Ensure that the motor is correctly connected to the drive

Carry out a motor data Autotune by setting P4-02 = 1
The Autotune will begin immediately when P4-02 is set regardless of the status of the drive enable signal. Whilst the autotune
procedure does not drive or spin the motor, the motor shaft may still turn slightly. It is not normally necessary to uncouple the
load from the motor; however the user should ensure that no risk arises from the possible movement of the motor shaft.
It is essential that the correct motor data is entered into the relevant drive parameters. Incorrect parameter settings can result
in poor or even dangerous performance.
