Just 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. The DCS4020 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. External input/output signals allow complete remote control of all drive functions. All electrical connections have removable plugs incorporating screw type terminals.
