6.1. Basic Recommendations
6.1.1.
General
1.
Use shielded cables. For best results, the cable should have an aluminum foil shield covered
by copper braid, and should contain a drain wire.
Use 24, 26 or 28 AWG twisted-pair shielded with drain wire cables.
2.
Keep the cable as short as possible.
Do not mount the power cables of the motor and power bus in the proximity of the control
and feedback cables.
3.
Ensure that in normal operating conditions, the “earth connection” wires and shield of the
control cables carry no current. The only time these conductors carry current is under
abnormal conditions, when electrical equipment has become a potential shock or fire
hazard while conducting external EMI interferences directly to ground, in order to prevent
them from affecting the drive. Failing to meet this requirement might result in
drive/controller/host failure.
4.
After completing the wiring, carefully inspect all wires to ensure tightness, good solder of
joints and general safety.

5.
Where there is only one COMRET pin (Common Return) in the connector, which MUST be
connected to the DRAIN WIRE and also to COMRET signal of the cable, it is necessary to
connect the drain wire and COMRET signal to the same pin.
