FAULT TRACING
How to correct the fault
Reset the fault. The device is ready
for use. The drive starts to use the
old parameter settings.
The device is not available. Reset
the fault.
Ask instructions from the distribu-
tor near to you.
Do a check of the loading.
Do a check of the motor size.
Make an identification run.
Set the deceleration time longer.
Use external brake resistor.
Do a check of the encoder connec-
tions.
Do a check of the encoder board.
Do a check of the encoder fre-
quency in the open loop.
