MELSERVO-J4

Low-Voltage Switchgear/Wires

Wires (Example of Selection for MR-J4W2-B and MR-J4W3-B) The following are examples of wire sizes when 600 V grade heat-resistant polyvinyl chloride insulated wires (HIV wires) are used. The wire size for U, V, W, and varies depending on the servo motor. Refer to "Selection Example in HIV Wires for Servo Motors" in this catalog for details on wires for each servo motor.

Over 252 W to 378 W S-T21 Notes: 1. Be sure to use a magnetic contactor with an operation delay time of 80 ms or less. The operation delay time is the time interval from current being applied to the coil until closure of contacts. 2. The wire size shows applicable size for the servo amplifier connector. 3. When complying with IEC/EN/UL/CSA standard, refer to "MELSERVO-J4 Instructions and Cautions for Safe Use of AC Servos" enclosed with the servo amplifier. 4. Refer to "MR-J4W2-_B MR-J4W3-_B MR-J4W2-0303B6 Servo Amplifier Instruction Manual" for selecting a molded-case circuit breaker and a magnetic contactor when combining multiple servo motors among the rotary servo motor, the linear servo motor or the direct drive motor. 5. Keep the wire length to the regenerative option within 5 m. 6. Install one molded-case circuit breaker and one magnetic contactor for each servo amplifier. 7. Use a molded-case circuit breaker having the operation characteristics equal to or higher than Mitsubishi Electric general-purpose products. Wires (Example of Selection for MR-J4W2-0303B6/MR-J4-03A6) The following are examples of wire sizes when 600 V grade heat-resistant polyvinyl chloride insulated wires (HIV wires) with a length of 30 m are used.
