1.2.1 Servo amplifiers 200V

Up to 750 W a 1-phase power supply is possible. For details of connecting the power
supply please see section 3.5.

The connection of terminals shown for the optional regenerative braking resistor applies
exclusively to servo amplifiers MR-J2S-350B or smaller. For exact descriptions of the
wiring of terminals for other performance classes, please see tab. 3-4.
