Goodrive350-19 Series VFD for Crane
2. Terminal master/slave mode b
The master adopts the speed control mode and sends the torque current to the slave HDIA terminal
through the HDO terminal. The slave adopts the torque control mode and the torque reference is set
by the HDIA terminal.

3. Analog terminal master/slave mode a
The master adopts the speed control mode and sends the ramp frequency to the slave AI1 terminal
through the AO1 terminal. The slave adopts the speed control mode and the frequency reference is
set by the AI1 terminal. Then, adjust reduction ratio of droop control P08.30 of the salve to meet
power balance.
