Drive Unit MD 24 / 28

General

The stepper motor drive units MD24/MD28 are high-capacity output stages for 2-phase and 4-phase stepper motors. The units are capable of microstepping and thereby allow for a silent run of the connected motors.
Special chopper technology of the motor current permits higher rotational speed and torques on motors comparable to common drive units.
The clock/direction interface allows for a simple connection to diverse motion controllers or to a SPS.
