With mechanically coupled motors it is very important that an even load distribution is applied to each motor. The load sharing can be achieved by enabling the droop function on both inverters.

1.Droop is applied as a frequency setpoint on each inverter.
The droop increases the slip via the negative feedback of the torque setpoint to the frequency setpoint. In a

-P1492 = 1
2.Droop can act as a setpoint or limitation for a group of inverters (i.e.
By use of the
This is accomplished by setting the torque setpoint (r1490) on the master inverter which then controls the frequency of the master inverter and all connected slave inverters.

Dependency:
Droop scaling (P1489) must be > 0 for droop to be effective.
