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.

Wire Sizes (Same for All Models)
Terminal
wire sizes are shown in Table 2.29.

Straight 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.
n
Closed-loop Connector Sizes and Tightening Torque
The
closed-loop connectors and tightening torques for various wire sizes are shown in Table 2.30.
n
Wiring 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.
