Wiring Method and Precautions

Observe the following precautions when wiring.
• Separate the control signal lines for the PG (Encoder) Feedback Board from main circuit lines and power lines.
Connect the shield when connecting a PG (Encoder). The shield must be connected to prevent operational errors
•
caused by noise. Also, do not use any lines that are more than 100m long. Refer to Fig 2.12 for details on
connecting the shield.
• Do not solder the ends of wires. Doing so may cause contact faults.
When straight solderless terminals are not used, strip the wires to a length of approximately 5.5mm.
•
Use shielded, twisted-pair wires for pulse inputs and pulse output monitor wires, and connect the shield to the shield
