The DCS4020 bipolar chopper drive has been designed for easy set up and use. It is ideal for development projectsjust connect a single power supply and a motor and the drive is ready to run. Motor current is set using an on-board potentiometer. No external current setting resistors are required. This feature-packed drive provides all basic motor controls including full or half stepping of bipolar steppers, directional control, and output enable control. An oscillator circuit is standard on the drive with an on board speed control potentiometer. In addition, external input/output signals allow complete remote control of all drive functions. All electrical connectors have removable plugs incorporating screw type terminals.
