Precautions for wiring

Precautions
• To avoid a malfunction, connect the power phases (U/V/W) of the servo amplifier and the direct drive motor correctly.
• To prevent a malfunction, do not connect AC power supply directly to the direct drive motor.
Refer to the following for the encoder cable.

This section explains the connection of the direct drive motor power (U/V/W). Use of the optional connector is recommended
for connection between the servo amplifier and direct drive motor. Refer to the following for details of the options.
Page 24 Wiring option
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.
