Servo amplifier

Model 7429AC servoamplifier uses digital PWM commands from PC-bus type motion controllers. The controllers' digital PWM commands provide direct control of motor operation. Switching action in the amplifier's power IGBT bridge circuit controls motor torque, speeds, and positioning. The amplifier develops 20A peak and plus or minus 10A continuous on ac-brushless servo motors up to 2.5 hp, and runs on 32V ac @ 50/60 Hz power. Applications include pick-and-place, automated assembly, and X-Y tables.
