Notes: 1. Rated output and rated speed of the servomotor used in combination with the servo-amp are as indicated when using the power-supply voltage and frequency listed. The output
capacity and speed cannot be guaranteed when the power-supply voltage is less than specified.
2. For torque characteristics when combined with a servomotor, refer to “servomotor torque characteristics” in this catalog.
3. For products without a dynamic brake (MR-J2S-
MA-ED or MR-J2S-MA1-ED), special compliance is possible.
4. It is possible to change the rotation speed in 10V using parameter No.25.
