Notes:

1. Rated output and speed of a servomotor are applicable when the servo amplifier, combined with the servomotor, 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 servomotor, refer to the section “Servomotor torque characteristics” in this catalog.

3. Optimal regenerative resistor varies for each system. Select the most suitable regenerative resistor by using the capacity selection software.

4. Refer to the section “Options • Optional regeneration unit” in this catalog for the tolerable regenerative power (W).

5. The servo amplifier (MR-J3-_KA-PX) without an enclosed regenerative resistor is also available.

6. 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: 1.0m³/min). Note that change in the parameter No. PA02 is required.

7. 300mA 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. Refer to “MR-J3-_A SERVO AMPLIFIER INSTRUCTION MANUAL” for details.

8. Special specification models without a dynamic brake, MR-J3-_A -ED and MR-J3-_A1-ED, are also available for 7kW or smaller servo amplifier.

9. The MR-J3-350A or smaller servo amplifier can be installed close together. In this case, keep the ambient temperature within 0 to 45°C (32 to 113°F), or use the servo amplifier with 75% or less of the effective load rate.

10. The special specification model, MR-J3-_A-U004, is also available for 1-phase 200 to 240 VAC.

11. 4Mpps compatible servo amplifier (MR-J3-_A(1)-KE) is also available.

12. High resolution analog speed command and analog torque command is available with a set of MR-J3-_A(1)-RJ040 and the extension IO unit, MR-D01.

13. When using the built-in dynamic brake, refer to “MR-J3-_A SERVO AMPLIFIER INSTRUCTION MANUAL” for the permissible load inertia moment ratio.
