The servo amplifier’s main circuit
power is supplied from the
converter unit.
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 when combined with a servo motor, refer to “servo motor torque characteristics” in this catalog.
