General Description
The MDC100-012101 driver is designed to drive DC brushless motors at currents of up to 10A (peak)
and 12V. Using hall sensor feedback, a constant velocity mode can be selected. The driver is protected
against over current (cycle-by-cycle), hall sensor error and under voltage. When an error occurs, a fault
light is turned on to notify the user. Included on the driver is an internal potentiometer to control the
maximum phase current allowed into the motor and an internal potentiometer to control the speed of the
motor. An optional external potentiometer (10K) or external voltage (0-4VDC) can be 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 dynamic brake and motor disable input. When using the brake input, it overrides all other
inputs into the driver.
Fault Protection
This driver is equipped with a FAULT LED to alert the user of the following conditions.
1. Invalid Sensor Input Code
2. Enable Input at Logic 0
3. Over Current. The driver is equipped with cycle-by-cycle current limiting or over current
latch.
4. Undervoltage Lockout activation at 9.1VDC for the input voltage and 4.5VDC for the
Hall Sensor voltage.

April 2012 L010364 Specifi cations Control Inputs: (TB3, Pins 3-5) TTL-CMOS Compatible Logic “0” = 0-0.8VDC Logic “1” = OPEN All three inputs (brake, enable and direction) are pulled up to through 40k ohm resistors. Freewheel: (TB2, Pin 5) Logic “1” (open) - Motor is Enabled Logic “0” - Motor is de-energized and will coast Direction Control: (TB2, Pin 4) Logic “1” (open) - Clockwise Logic “0” - Counterclockwise Brake: (TB2, Pin 3) Logic “1” (open) - Motor will not run and if running will decelerate rapidly Logic “0” - Motor will run Output Current Rating: Adjustable 1.0 - 10.0 amperes per phase maximum operating peak current (0.5 - 5.0 amperes per phase maximum operating continuous current) Power Requirements: (TB2, Pins 1 and 2) 10VDC (min) - 15VDC (max) Operating Temperature Heat Sink: 0°-70° C Hall Sensor Power Output: 6.25V @30mA maximum. Typical current draw from hall sensors in 20mA. All three Hall Sensor inputs are pulled up through 20K ohm resistors. The external speed control potentiometer must be 10K Ohms. Heating Considerations The temperature of the heat sink should never be allowed to rise above 70°C. If necessary, mount the unit to an additional heat sink or are should be blown across the heat sink to maintain suitable temperatures.

When connecting a motor for the fi rst time, connect the hall sensor wires (5 of them) to the driver. DO NOT CONNECT THE PHASES YET. Turn on power and rotate the motor by hand. If the RED FAULT LED comes on, the hall phases are incor- rectly wired. If the RED FAULT LED does not come on then the hall wires are connected correctly. Power the unit down and proceed to connect the motor phases. If the motor does not run or runs erratically, power down and check the speed potentiometer and make sure the phases are connected correctly. There are six different ways to connect the phase wires, and normally only two will allow the motor to rotate, but only one is correct. If the direction of the motor is changed and the no-load current of the motor is approximately the same and the motor runs smoothly in both directions then the phase wires are correct. The wiring of the motor phases should be separated from the hall and input connections to not allow a possible source of interference.

One is to use the on board potentiometer. The other is to use an external 10k potentiometer. To use the on board potentiometer, set jumper JP2 to position 1-2 (default). To use the external 10K potentiometer, set jumper JP2 to position 2-3. The mating connector for the external 10K potentiometer is Molex part number 3-640440-3. Motor Enable The motor enable 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. Motor Brake The motor brake feature allows the stopping of a motor by shorting out the bottom drives of the three phases. A low at this input allows the motor to run, while an open input does not allow motor operation and if operating causes rapid deceleration. 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.
