CONNECTION OF SERVO AMPLIFIER AND
DIRECT DRIVE MOTOR
Precautions
• Insulate the conductive parts of the terminals.
• To prevent an unexpected operation of the direct drive 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.
• Do not install a power capacitor, surge killer, or radio noise filter (optional FR-BIF) on the power wire of the direct drive
motor.
• To prevent an abnormal operation and a malfunction of the direct drive motor, connect the servo amplifier power output (U/
V/W) to the direct drive motor power input (U/V/W) directly. Do not connect a magnetic contactor and others between them.

• 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 direct drive motor with the specified servo amplifier.
• Do not modify the equipment.
• To prevent malfunction, eliminate static electricity before wiring, switch operation, or others.
• 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 direct drive motor. Therefore, the recommended wire
sizes may differ from those of the used wires for the previous direct drive motors.
