Warning!
This product can cause high-frequency interference in residential areas, which could
require measures for radio interference suppression.
EMC-compliant cabling
The following must be considered for an EMC-compliant setup of the drive system:
•
In order to keep the leakage currents and the losses in the motor connection cable as small as
possible, the servo positioning controller should be located as close to the motor as possible.
•
Motor cable and angle encoder cable must be shielded.
•
The shield of the motor cable is connected to the housing of the servo positioning controller. The
cable shield also has to be connected to the associated servo positioning controller so that the
leakage currents can flow back into the controller causing the leakage.
•
The mains-end PE connection and the inner PE conductor of the motor is connected to the PE
connection point of the supply connection
•
The signal lines must be as far away from the power cables as possible. They should not be
placed parallel. If intersections cannot be avoided, they should be perpendicular (i.e. at a 90°
angle), if possible.
