Selection of Control Circuit Wirings
All control wirings must be shielded.
For different analog signals, use independent shielded cables and do not use the same
shield.
For digital signals, shielded twisted pair (STP) cable is recommended.

Cabling Requirements
Ɣ
Motor cables must be segregated from control wiring to minimize electrical
interference from the PWM effects of the motor cable.
Ɣ
Do not run motor cables, power input cables and control wirings in the same duct to
avoid electromagnetic interference caused by coupling of these cables.
Ɣ
If control wiring must run across power cable, ensure they are arranged at an angle of
90°.
The recommended cabling diagram is as follows:
