Note: 1. The servo motor output values and rated speeds assume the power supply voltage and frequency indicated in the
tables. They cannot be guaranteed when a power supply voltage drop occurs.
2. For the compatible motors, refer to the Servo Motor Instruction Manual as they are the same as those of the MR-
J2S-A Servo.
