1388-AV40

The 1388-AV40 controller is an industrial servo controller that is designed and manufactured by Allen-Bradley/Rockwell Automation. This Bulletin 1388 product is part of Series A of these kinds of controllers and it is designated as a DC pulse width modulated (PWM) controller. This transistorized controller is built on the basis of semiconductor technology that offers great performance capabilities. The 1388-AV40 servo controller comes in a modular package and it is a self-contained unit with a wide range of standard features for various automated machines or application processes. The controller has a flexible interface and it is compatible with programmable controller products and other control equipment from Allen-Bradley. The 1388-AV40 servo controller is built for integration with DC permanent magnet servo motors and it has advanced capabilities in regard to adjustments and configuration capabilities.

Using the 1388-AV40 servo controller will enhance the overall system since the controller has features such as motor thermal overload detection (MODR) and torque taper circuits or a speed-dependent current limit. One of the advantages of these functions is that they can work simultaneously with the same potentiometer. Other standard features of the controller include a line/DB contactor, MOV protected input, an input line circuit breaker, multiple diagnostics and test points, and logic supply under voltage detection. The 1388-AV40 servo controller features a nominal output voltage under load rating of 150 Volts DC and a continuous current rating of 40 Amps continuous and 100 Amps peak. The unit comes with an open frame and an internal heatsink. Even though the 1388 product series provides optional elements and special modifications, this model is a basic model with factory-standard features.
