2. Motor and master/slave switchover work conditions
For example, in the lifting job of port crane, VFD 1 as the master drives lifting motor 1, while VFD 2 as
the slave drives lifting motor 2. After completing the lifting job, VFD 2 needs to drive the trolley motor
independently. At this time, the master/slave mode must be disabled for VFD 2, and the parameters of
lifting motor 2 and trolley motor must be switched also, while VFD 1 can still use the master/slave
mode.
Note: The power supply switchover of lifting motor 2 and trolley must be controlled by the
PLC.
