◆ Wiring the Control Circuit Terminal

Observe the following precautions when wiring control circuits.
• Use shielded twisted-pair wires for analog I/O (terminals L1 to L9) wirings to prevent malfunctions caused by noise.
• Tighten all terminal screws to the specified tightening torque.
• Use round crimp terminals to connect signal wires to the terminal block.
• Use a Phillips screw driver to tighten terminal screws.
WARNING! Electrical Shock Hazard. Do not touch circuit boards while the power is on. Failure to comply could result in death or
serious injury.
NOTICE: When wiring the control circuit, separate it from the main circuit wiring (terminals R, S, T, U, V and W) and other power lines.
Improper grounding could result in drive malfunction.
NOTICE: Insulate the shielded wires of the drive, e.g. with tape, to prevent their contact with other signal lines or devices. Failure to
comply could result in drive or equipment malfunction due to short circuit.
