Product Description
The Bulletin 1388 is a transistorized servo controller which utilizes advances in power semiconductor technology to provide high performance in a modular package. The controller will handle MOST DC permanent magnet servomotors with simple on site adjustments and setup. The controller contains a number of features which enhance servomotor operation including integral electronic Motor Thermal Overload Detection ( MODR) and Torque Taper Circuits. The thermal overload detection trip and torque taper circuits are set simultaneously with the same potentiometer.
