Droop Control
The droop control function aims at balancing the load level of two motors that drive the same
load. This function is required only when both master and slave are in speed control.
A proper droop rate is gradually obtained during drive running. Therefore, do not set F8-15 to a
very large value. Otherwise, steady speed will decline obviously when load is very large. You must
set this parameter in both master and slave.
