Wiring Terminal Blocks

Use no more than 30 meters of wiring for PG (encoder) signal lines for the 3G3FV-PPGA2/PPGB2 or 50
meters for the 3G3FV-PPGD2/PPGX2, and keep the wiring 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.
nWire Sizes (Same for All Models)
Terminal wire sizes are shown in Table 2.29.

nStraight Solderless Terminals for Control Circuit Terminals
We recommend using straight solderless terminal on signal lines to simplify wiring and improve reliability.
Refer to Table 2.15 Straight Solderless Terminal Sizes for specifications.
nClosed-loop Connector Sizes and Tightening Torque
The closed-loop connectors and tightening torques for various wire sizes are shown in Table 2.30.

nWiring Method and Precautions
The wiring method is the same as the one used for straight solderless terminals. Refer to page 2-30. 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 longer than the recommended length. Refer to Fig 2.26
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.
