1. 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.
