CONNECTION OF SERVO AMPLIFIER AND
ROTARY SERVO MOTOR
Precautions
• Insulate the conductive parts of the terminals.
• To prevent unexpected operation of the rotary servo motor, wire the equipment correctly and securely.
• Make sure to connect the cables and connectors by using the fixing screws and the locking mechanism. Otherwise, the
cables and connectors may be disconnected during operation.
• To prevent abnormal operation and malfunction, connect the servo amplifier power output (U/V/W) to the rotary servo motor
power input (U/V/W) directly. Do not connect a magnetic contactor or the like between the servo amplifier power output and
the rotary servo motor power input.

• To prevent a malfunction, do not connect AC power supply directly to the rotary servo motor.
• When the wires are not tightened enough to the terminal block, the wires or terminal block may generate heat because of
the poor contact. Be sure to tighten the wires with specified torque.
• Use the rotary servo motor with the specified servo amplifier.
• Do not modify the equipment.
• To prevent malfunction, eliminate static electricity before wiring, switch operation, or similar operations.
• To prevent failure and malfunction, only the power/signal specified in the user's manual should be connected to each
terminal.
• We recommend using HIV wires to connect the servo amplifier to the rotary servo motor. Therefore, the recommended wire
sizes may be different from those of the wires used for previous generation rotary servo motors.
