Notes: 1. Rated output and speed of a servo motor are applicable when the servo amplifier, combined with the servo motor, is operated within the
specified power supply voltage and frequency. Torque drops when the power supply voltage is below the specified value.
2. For torque characteristics when combined with a servo motor, refer to the section “Servo motor torque characteristics” in “MELSERVO-J3
catalog L(NA)03017”.
3. 200mA is the value when all of the input/output points are used. The current capacity can be stepped down according to the number of
input/output points in use.
4. The value in ( ) applies when the external regenerative resistors, GRZG400-Ω (standard accessory) are used with cooling fans (2 units
of 92 x 92mm, minimum air flow: 1.0m
3
/min). Note that change in parameter No. PA02 is required.
5. Servo amplifiers without an enclosed regenerative resistor are also available: MR-J3-S4-PX.
6. Special specification servo amplifiers without a dynamic brake are also available: MR-J3-S4-ED.
7. The amplifier built-in resistor is compatible with the maximum torque deceleration when the motor is used within the rated speed and the
recommended load to motor inertia moment ratio. Contact your local sales office if the operating motor speed and the load to motor inertia
moment ratio exceed the rated speed and the recommended ratio.
8. When using the built-in dynamic brake, refer to “MR-J3-B Safety MR-J3-D05 SERVO AMPLIFIER INSTRUCTION MANUAL” for the
permissible load inertia moment ratio.
