The Allen-Bradley/Rockwell Automation 1388-AV60 servo controller, part of the Series A lineup, is engineered for industrial applications requiring precision and reliability. Featuring advanced power semiconductor technology, this modular unit works seamlessly with 1326 series inductors, isolation transformers, and PM servo motors. It includes torque taper circuits, a PWM servo amplifier, and comprehensive diagnostics, ensuring optimal performance. Capable of handling continuous and peak currents of 60 Amps and 150 Amps respectively, it delivers a nominal output of 150 Volts DC, with a power capacity of 4.5 kW continuous and 22.5 kW peak. Equipped with a 0.75 Ohms internal dynamic braking resistor, the controller offers robust protection with RMS armature thermal overload detection and MOV input safeguarding. Operating efficiently between 0 to 60 degrees Celsius, the 1388-AV60 is an ideal choice for environments demanding durability and high output.
