The MBDCKB1-120081 driver is designed to drive DC Brush motors at currents of up to 8A (peak) and 90-180V. The driver is protected against over-current (cycle-by-cyle) and under-voltage. When an error occurs, a fault light is turned on to notify the user. Internal potentiometers allow the user to control the maximum phase current allowed into the motor, as well as ramp-up timing. An external potentiometer (10K) is used to control the speed as well. The direction of the motor can be preset by the direction control input. Other inputs to the drive include a run/stop and a motor enable input. When in use, the run/stop input overrides all other inputs into the driver.
