Wiring Terminal Blocks
Use no more than 100 meters (328 ft) of wiring for PG (encoder) signal lines, and keep them separate from
power lines.
Use shielded, twisted-pair wires for pulse inputs and pulse output monitor wires, and connect the shield to the
shield connection terminal.
Wire Sizes (Same for All Models)
Terminal wire sizes are shown in Table 2.19.
Straight Solderless Terminals for Control Circuit Terminals
We recommend using straight solderless terminals on signal lines to simplify wiring and improve reliability.
Closed-loop Connector Sizes and Tightening Torque
The closed-loop connectors and tightening torques for various wire sizes are shown in Table 2.20.
Wiring Method and Precautions
Observe the following precautions when wiring.
• Separate the control signal lines for the PG Speed Control Card from main circuit lines and power lines.
• Connect the shield when connecting to a PG. The shield must be connected to prevent operational errors
caused by noise. Also, do not use any lines that are more than 100 m (328 ft) long. Refer to Fig 2.17 for
details on connecting the shield.
• Connect the shield to the shield terminal (E).
• Do not solder the ends of wires. Doing so may cause contact faults.
• When not using straight solderless terminals, strip the wires to a length of approximately 5.5 mm (0.2 in).
