Droop control automatically balances the load level between two motors that operate the same load.
Droop control decreases motor speed as the load changes. You must enable the Droop control function for each motor it is operating.
To decrease motor speed, the Droop control function decreases the speed reference when an increase in the load increases the torque reference. To increase motor speed, the Droop control function increases the speed reference when a decrease in the load decreases the torque reference. The Droop control function adjusts motor speed as the torque reference changes to balance the load between the motors.
Note:
When you use Droop control, set n5-01 = 0 [Feed Forward Control Selection = Disabled].
