Chapter 1. Setting Up
Wiring Notes
1.
To reduce noise problems, the AC117V and the DC24V external power cable should be a twisted pair.
2.
Isolate the SEL cables from the power line.
3.
For DC motors, isolate the encoder cable from the motor cable.
4.
For AC motors, the motor and encoder cables are partially wired together but when the length of the cable
extends more than 5m, please wire them separately.
5.
Consult with IAI if you need to extend the motor and encoder cables beyond the length that comes with the
controller.
