Drive modules MD 24 / 28

The step motor drive modules MD24/MD28 are powerful final stages for 2-phase and 4-phase step motors.

The modules are micro-step capable and thus allow very quiet running of the connected motors. Due to its particular chopper technology for the motor current, identical motors can deliver higher speeds and torques than conventional, comparable drive modules. 

The clocking/direction interface also allows simple connection to various motion controllers or a PLC.
