I am experiencing positioning errors with AKM1 motors. What can I do?

Low rotor inertia is the source for this problem, ironless linear motors show a similar behavior.

Solution for drives with S300/S700 servo amplifiers:

Increase the bandwidth of the current control loop with the Smith Predictor (FILTMODE = 2). Refer to page Tuning: Delay Time Compensation with Smith Predictor.
