B8: Energy Saving - Omron Q2A Series Technical Manual

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 [FF Control Selection = Disabled].
