Goodrive350-19 Series VFD for Crane
drives lifting motor 2. After completing the lifting job, VFD 2 needs to drive the cross travel mechanism
motor independently.
To do this, VFD 2 needs to:
(1) Disable the master/slave mode and run independently.
(2) Switch the motor from lifting motor 2 to the cross travel mechanism motor.
(3) Switch motor and VFD parameters.

Note: The power supply switchover of lifting motor 2 and the cross travel mechanism motor
must be controlled by the PLC.
Commissioning procedure:
1. Set P90.00=6 (User-defined macro 1) for VFD 2, set running parameters for lifting motor 2
according to the following table of user-defined application macro parameter settings, and note
that A81.24=2 (Slave mode).
2. Set P90.01=7 (User-defined macro 2) for VFD 2, set the parameters for cross travel mechanism
motor according to the following table of user-defined application macro parameter settings, and
note that A81.24=0 (Disable master/slave mode).
3. When the S1 terminal of VFD 2 is invalid, VFD 2 drives lifting motor 2 and VFD 1 drives lifting
motor 1 to complete the lifting work. When the S2 terminal of VFD 2 is valid, VFD 2 independently
drives the cross travel mechanism motor to work.
