Goodrive350-19 Series VFD for Crane
Note:

At certain faults that cannot be reset, such as VFD internal hardware damaged, zero servo
cannot be entered. At the faults that can be reset, with zero servo conditions met, zero servo can
be entered.

Every time zero servo is exited, torque verification is not performed only at the first running
command giving, which means the verification is performed at all the following running command
giving.

When P93.02 ones place=2, the motor becomes hot, the fan cannot be mounted at the same
shaft as the motor, and it must be independently controlled.
The following faults cannot be reset:
