Notes: 1. Dynamic brake which is built in servo amplifiers is removed. When using the servo amplifier without a dynamic brake, the servo motor does not stop immediately at alarm occurrence or power failure. Take measures to ensure safety on the entire system. Refer to relevant Servo Amplifier Instruction Manual for details. 2. A-axis, B-axis, and C-axis indicate names of axes of the multi-axis servo amplifier. The C-axis is available for the 3-axis servo amplifier. 3. Supported by MR-J4W2-0303B6 servo amplifier. 4. The special coating (JIS C60721-3-3/IEC 60721-3-3 classification 3C2) is applied to the circuit board of the servo amplifier and the drive unit of 30 kW or larger. Refer to relevant Servo Amplifier Instruction Manual for details. 5. A power supply of 3-phase 200 V AC is supported by 37 kW or smaller drive units. 6. Available only with MR-J4-DU_B_(-RJ). 7. Positioning mode is supported by MR-J4-DU_A_-RJ drive unit. 8. MR-J4-DU_B_-LL is available in 30 kW or larger drive units. Refer to "MR-J4-_B_-LL MR-J4-DU_B_-LL Servo Amplifier Instruction Manual" for the pressure control compatible servo amplifiers. 9. A power supply of 1-phase 200 V AC is supported by 0.2 kW to 0.75 kW servo amplifiers. 10. For the servo amplifier/drive unit software version which supports each function, refer to the specification page of each unit. 11. Available only with 0.2 kW and 0.4 kW.
