Notes: 1. Rated output and speed of a rotary servo motor are applicable when the servo amplifier, combined with the rotary servo motor, is operated within the specified power supply
voltage and frequency.
2. Select the most suitable regenerative option for your system with our capacity selection software.
3. Refer to "MR-J4-_B_-RJ020 MR-J4-T20 Servo Amplifier Instruction Manual" for the tolerable regenerative power [W] when regenerative option is used.
4. When using the built-in dynamic brake, refer to "MR-J4-_B_-RJ020 MR-J4-T20 Servo Amplifier Instruction Manual" for the permissible load to motor inertia ratio.
5. Terminal blocks are excluded.
6. The servo amplifier built-in regenerative resistor is compatible with the maximum torque deceleration when the servo motor is used within the rated speed and the
recommended load to motor inertia ratio. Contact your local sales office if the operating motor speed or the load to motor inertia ratio exceeds the rated speed or the
recommended ratio.
7. The value is applicable for the MR-J4-_B4-RJ020 servo amplifier only.
8. The value in brackets is applicable when cooling fans (2 units of 92 mm × 92 mm, minimum air flow: 1.0 m
3
/min) are installed, and then [Pr. 2] is changed.
9. Servo amplifiers without an enclosed regenerative resistor are also available. Refer to "Servo Amplifier Model Designation" in this brochure for details.
10. Use an optional external dynamic brake with the servo amplifier. Without the external dynamic brake, a servo motor does not stop immediately at emergency stop and falls
in free-run status, causing an accident such as machine collision, etc. Take measures to ensure safety on the entire system when not using the dynamic brake.
