6.3 Motor Cable
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.
The protective earth wire (green/yellow) of the motor cable should be connected to the
earthing screw near the motor connector of the MSX plug-in power stage unit. The
green/yellow wire should be connected to the motor's earthing screw at the other motor
cable end.
We recommend the following lead cross section of the motor cable
:
1.50 mm
2
For best electromagnetic compatibility (EMC), you should connect the shielding
mesh to the MSX housing. Use the cable clamps on the rear side of the MSX
power supply unit. The free cable ends must be as short as possible.
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 or 4)!
