Precautions for wiring

Precautions
• To avoid a malfunction, connect the wires to the correct phase terminals (U/V/W) of the servo amplifier and the linear servo
motor.
• To prevent a malfunction, do not connect AC power supply directly to the linear servo motor.
For grounding, connect the grounding lead wire from the servo motor to the protective earth (PE) terminal of the servo
amplifier, and then connect the wire from the servo amplifier to the ground via the protective earth of the cabinet. Do not
connect the wire directly to the protective earth (PE) terminal of the cabinet.

Power supply cable wiring diagrams

To wire to the servo amplifier, use connectors packed with the servo amplifier or optional connectors.
For connectors, refer to "Wiring CNP1, CNP2, and CNP3" in the following manual.
