6.4 Motor Cables
We recommend to wire the stepper motor with a 5-lead cable with shielding mesh. For
optimum electromagnetic compatibility (EMC), the cable should not be interrupted by
additional connectors or screw terminals. We recommend to use a short motor cable
because of EMC. See chap. 6.1 and 6.2.
The protective earth wire (green/yellow) of the motor cable should be connected to the
earthing screw near the MCD motor connector. At the other motor cable end, the
green/yellow wire should be connected to the motor's earthing screw (if available).
For best electromagnetic compatibility (EMC), you should connect the shielding mesh to
the MCD housing. Use the cable clamps at the bottom and the top side of the MCD.
The shielding mesh should also be connected on a large surface to the motor housing.
Use EMC-type conduit fittings. All parts of the motor should be conductively connected
with each other. We recommend to use EMC conduit fittings at the motor side.
In case of motors without adapted conduit fittings the cable shielding must be connected
as near to the motor as possible and has to be applied to PE.
Important:
Motor leads not used should be insulated separately
(important if using wiring scheme 3,4 or 5)!
