August 2008 L010513 General Description The MBDC050-024031 driver is designed to drive DC brush motors at peak currents of up to 3.0A and 35V. An optional external potentiometer (10K) or external voltage (0.5-5VDC) can be used to control the speed as well. The direction of the motor can be preset by the direction control input. To disable energy from the motor, their is a Freewheel input that can be grounded. Fault Protection The fault protection is set for a cycle by cycle motor turn-off. Cycle by cycle over current limiting is done by monitoring the peak motor current and upon an over current of 3A, the motor phases are immediately turned off and held off for the remainder of the internal PMW oscillation. MBDC050-024031 Driver Features • Current Limit set at 3.0 Amps • External Potentiometer Speed Control • 0.5V to 5V External Voltage Speed Control • 2-Quadrant Operation • Open-Loop Velocity Mode • Cycle by Cycle Short Circuit Protection • Requires 8 - 35VDC • Freewheel and Direction Inputs • TTL-CMOS Compatible Inputs • Compact Size (1.50”x1.50”x0.712”) • Screw type Terminal Block Ordering Information # t r a Pn o i t p i r c s e D 1 3 0 4 2 0 - 0 5 0 C D B MV6 3 - 8 , A 3 , r e v i r D C D B A 7 . 2 V 4 2 A S Psp m A 7 . 2 t a C D V 4 2 y l p p u S r e w o P C D Specifications Vspeed Control: (TB1, Pin 1) 0VDC - Motor Stopped 5VDC - Max Speed (6VDCmax) Control Inputs: (TB1, Pins 2-3) TTL-CMOS Compatible Logic “0” = 0-0.8VDC Logic “1” = OPEN All inputs (enable and direction) are pulled up through 10k ohm resistors.

If necessary, air should be blown across the heatsink to maintain suitable temperatures.
August 2008 L010513 Speed Adjust Setting There are two ways to set the speed on this drive. One is to use an external voltage from 0.5 - 5V. The other is to use an external 5V PWM signal from 7KHz to 10KHz. . To use the external voltage control function, set jumper JP1 to position 1-2 (default). To use the iexternal 5V PWM, set jumper JP1 to position 2-3. Motor Direction The motor direction feature allows the changing of the rotation of the motor. This input should not be changed while motion is in progress. An open input causes the motor to turn in the CW direction, while a low at this input causes the motor to turn in the CCW direction. Motor Freewheel The motor freewheel feature allows the de-energizing of the motor phases. An open input at this input causes the motor to run at the given speed, while a low at this input causes the motor to coast to a stop.
