Notes: 1. Rated output and rated speed of the servo motor used in combination with the servo amplifier are as indicated when using the power supply voltage and frequency listed. The torque
drops when the power supply voltage is less than specified.
2. For torque characteristics applied when the servo amplifier is combined with a servo motor, refer to “servo motor torque characteristics” in this catalog.
3. The special specification model without a dynamic brake, MR-J2S-
MA-ED or MR-J2S-MA1-ED, is also available.
4. The speed in 10V can be changed with the parameter No.25.
