6.3 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.
Recommended minimum cable cross section: 0.2 mm²
(0.1 mm² per Ampere motor current)
The protective earth wire (green/yellow) of the motor cable should be connected to the
earthing screw near the CLD
+
motor connector. At the other motor cable end, the
green/yellow wire should be connected to the motor's earthing screw.
The phase currents are leaded outside through a motor lead filter to damp the logic’s high
frequency noise signals. So the noise emission on the motor cables is nearly neglectable.
For best electromagnetic compatibility (EMC) , you must connect the shielding
mesh to the CLD
+
housing. Use the cable clamps at the front side. Free cable
ends must be as free as possible.
The shielding mesh must also be connected on a large surface to the motor
housing. Use EMC-type conduit fittings. All parts of the motor must be
conductively connected with each other.
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 or 4)!
If the motor is connected in the required way, the fault-free operation is assured according
to EN 61000-6-1/2.
The manufacturer of the equipment/machine is responsible for the adherence to limit
values, required by the EMC legislation.
