Layout of the power cable connection terminals and lead-throughs
(frames R6 to R9)
Note:
If there is a symmetrically constructed grounding conductor on the motor cable in addition to the conductive
shield, connect the grounding conductor to the grounding terminal at the drive and motor ends.
Do not use an asymmetrically constructed motor cable. Connecting its fourth conductor at the motor end
increases bearing currents and causes extra wear.
