5.14.3 Master/slave communication

The VFDs can implement the master/slave control function by using the CAN master/slave
communication card. The wiring diagram is as follows.

The specific CAN communication master/slave modes are: master/slave mode 0–2 are master/slave
power balance modes, master/slave mode 4 is the master/slave speed synchronization mode, and
master/slave mode 3 is reserved. Master/slave mode 0 and master/slave mode 1 are used often.
