Motor power connection
Only electronically commutating synchronous motors (brushless dc motors, EC motors) with resolver or
incremental encoder must be used. These motors must be approved of by the manufacturer prior to any
use.

Motor choke
Only necessary for a shield capacity of >5 nF. Approx. 25m motor cable
Magnetic rings:
Against HF failures of the sensor systems. Slide the rings onto the motor lines.
Connection of the shield
Surface-to-surface connection to the switch cabinet inlet.
Surface-to-surface connection as short as possible to the motor side.
For long motor cables, connect the motor cable shields to ground several times
(mounting frame) (e.g. ground connection every 2 meters).
