General Description

The MDCSL100-050301 driver is designed to drive DC brushless motors without using hall sensors at

currents of up to 30A (peak) and 50V. The driver is protected against over current (cycle-by-cycle or

latched) and under voltage. When an error occurs, a fault light noties the user. If an error occurs, the

fault output goes low 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 (1-5VDC) 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 run/stop and a motor freewheel input. When using the run/stop input, there are three

ramp up proles from standstill to select from. The run/stop input overrides all other inputs into the driver.

Fault Protection

If a motor current level exceeding the current limit set by the internal or external current limit potentiom-

eter is produced, an over current latch is activated, shutting off the output and turning the fault output

low (logic “0”). When a fault is detected, the driver turns off the motor current, the red FAULT LED

alerts the user a fault occurred and the Fault Output (TB3 - Pin 5) goes low. The Fault Output is dis-

abled, logic ‘1’ output. This Fault protection alerts the user of the following conditions.

1. Over Current. The driver is equipped with cycle-by-cycle current limiting or over

current latch.

2. Undervoltage Lockout activation at 9.1 VDC for the input voltage

Specications (cont.)

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

Run/Stop: (TB2, Pin 3)

Logic “1” (open) - Motor will not run and if running will come to a hard stop

Logic “0” - Motor will run and will accelerate according to ramp dip switch setting

Fault Output: (TB2, Pin 1)

5V Pull-up required.

Logic “1” (5V out) - Status good, normal operation.

Logic “0” - One of the three fault conditions listed in the ‘Fault Protection’ section has occurred.

Vcontrol: (TB2, Pin 2)

To control the speed of the motor with an external DC voltage, INT/EXT SPD switch (SW1-POS1) must

be switched to the ON position. 0VDC (min) - 5VDC (max)

Output Current Rating:

Adjustable 10.0 - 30.0 amperes per phase maximum operating peak current

(5.0 - 15.0 amperes per phase maximum operating continuous current)

Power Requirements: (TB2, Pins 1 and 2)

20VDC (min) - 50VDC (max)

Operating Temperature

Heat Sink: 0°-70° C

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 air should be blown across the heat sink to maintain suitable temperatures.

Motor Connection

Refer to the hookup diagram for typical driver applications. 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.

Motor Freewheel

The motor freewheel feature allows the de-energizing of the motor phases. A high (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 Run/Stop

The motor run/stop 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 a high (open) input does not allow motor opera-

tion 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. A high (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.

L011693

Speed Adjust Setting

There are two ways to set the speed on this drive. One is to use the on board potentiometer. The other

is to use an external 10K potentiometer. To use the on board potentiometer, set switch SW1 to the off

position (default). To use the external 10K potentiometer or external 1V to 4V voltage speed setting, set

switch SW1 to the on position. A voltage of 1V-4V to control the speed of the motor can be tied to the Pot

Wiper connection of P1 with 0V tied to pin 6 of TB2 (GND). The maximum voltage that can be placed on

the pot wiper with respect to ground is 6V.

The mating connector for the external 10K potentiometer is Molex part number 3-640440-3.

Fault Output

The Fault Output requires a 5V pull-up to work correctly. The Fault Output indicates an over current or

failure in the motor/driver operation. The Fault Output is normally at a logic level 1(5V). If a fault occurs,

the Fault Output will go to a logic level 0(0V).
