Might be your Group 2 motor parameters, did you set the correct motor parameters. Did you try to run auto tuning of the motor? It would need to be done static (02-07 = 1) unless there is a neutral gear selection. You should be running in SLV mode, not V/F.
To start auto tuning procedure in SLV mode:
- Set motor parameters 02-01 and 02-03~02-06,next set 02-07 to【1】to start the auto tune procedure.
- During the Auto tune the display will show AT and show END briefly when auto tune is completed then the
display will return back to show frequency.
- After a successful auto tune the motor test data is stored in parameters 02-08 and 02-09 and parameter 02-07 is
set back to 0.
Notes:
- Perform an auto tune whenever the motor is replaced.
- Auto tuning is not possible for applications with multiple motors connected to one inverter.
- Auto tune can be used on motors of similar size to the inverter or one size smaller. Make sure to set the correct
motor parameters.
- Parameters 02-00 ~ 02-06 are available both for V/F & SLV mode (Except parameter 02-02 V/f only).
