What is an OPF2 on an ATV320 drive?

Product Line:
Altivar 320
Motor is not connected, output contactor (if used) is not closing fast enough, or the motor current draw is too low.
Check all the output connections from the drive to the motor.
Check all the motor parameters and make sure the set values match the motor nameplate data. 
Check to see if there is an output contactor between the output of the drive and motor connector is probably open. If an output contactor is used, go to menu CONF, FULL, FLT-, OPL and set Output Phase loss to No.

Test the drive without the motor connected:
  1. Set OPL to No.
  2. Power down and disconnect the motor from the drive's terminals.
  3. With the motor disconnected, run the drive at 20, 30, and 60Hz and measure the output voltages phase-to-phase to see if they are all balanced.
  4. With the motor disconnected, megger out the motor with 1,000V Megger.
