B.1. Wiring Precautions

To ensure safe and stable operation, always observe the following wiring
precautions:
1. Always use the following cables for reference input and encoder
wiring.
- Cable Type
Reference Input Twisted pair wires
Multi-conductor
Encoder shielded twisted air
wire
• Trim off the excess portion of the cable to minimize the cable
2. For a ground wire use as large a wire as possible: AWG14 (2.0mm
or larger.
• At least class-3 ground (100Ω. maximum) is recommended.
• Ground to one point only.
• If the motor is insulated from the machine, ground the motor
3. Do not bend or apply tension to cables.
The conductor of a signal cable is very thin (0.0079 to 0.012in. (0.2
to 0.3mm)), handle the cables with care.
4. Use a noise filter to prevent noise interference.
(For details, refer to 5.8.2 Wiring for Noise Control).
