							General Description
The MDC100-050101 driver is designed to drive DC brushless motors at currents of up to 10A (peak) 
and 50V.  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 volta\
ge.  When an error occurs, a fault 
light is turned on to notify the user.  Included on the drive 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 (1.5-4VD\
C) 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 a 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 curr\
ent    
   latch.
4.  Undervoltage Lockout activation at 9.1VDC for the input voltage and 4.5V\
DC for the    
    Hall Sensor voltage.

Speed: (JP3 or R13):
Internal/External Speed Potentiometer: 30% -100%
External Voltage: 1.5V - 4V
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)
20VDC (min) - 50VDC (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.
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.

							Commutation Sequence
+ = Top Transistor ON, Bottom Transistor OFF, Current flows into this wire
- = Top Transistor OFF,  Bottom Transistor ON, Current flows out of this wire
Z = Top Transistor OFF, Bottom Transistor OFF,  No current into or out of this wire (High Impedance)
Motor Connection
Refer to the hookup diagram for typical driver applications.  When connecting a motor for the first 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 bo\
th directions then the phase 
wires are correct.
The wiring of the motor phases should be separated from the hall and inp\
ut connections to not allow a 
possible source of interference.

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 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 nu\
mber 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 ca\
uses the motor to coast to a 
stop.
Motor Brake
The motor brake feature allows the stopping of a motor by shorting out t\
he 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 m\
otor.  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.
