Interface
All conductors must be enclosed in one shield with a jacket around them. The shield on the drive end of the
motor power cable should be terminated to the conductive machine panel using screen clamps as shown in
section 3.2. The other end should be properly terminated at the motor shield. Feedback cable shields should
be terminated in a like manner. Lenze recommends Lenze cables for both the motor power and feedback.
These are available with appropriate connectors and in various lengths. Contact your Lenze representative
for assistance.
