Function

In synchronous servomotors with permanent magnets, torque fluctuations occur due to design-related asymmetries, which have a particular effect at low speeds. The servomotor becomes unstable as a result. The cogging torque compensation improves the synchronization characteristics of the servomotor considerably by applying compensation torques.

By default, the function is always switched on, provided that the servomotor is equipped with the corresponding compensation parameters. Below a speed of 500 rpm, the speed fluctuation is reduced significantly.
