Specifi cations
Control Inputs: (TB1, Pins 1-3)
TTL-CMOS Compatible
Logic “0” = 0-0.8VDC
Logic “1” = OPEN
All Three inputs (run/stop, freewheel, and direction) are pulled up through 10k Ohm resistors.
Direction Control: (TB1, Pin 1)
Logic “1” (open) - Clockwise
Logic “0” - Counterclockwise
Freewheel: (TB1, Pin 2)
Logic “1” (open) - Motor is Enabled
Logic “0” - Motor is de-energized and will coast to a stop
Run/Stop: (TB1, Pin 3)
Logic “1” (open) - Motor will not run
Logic “0” -...

Freewheel
The motor freewheel feature allows the de-energized 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 operation and if operating causes...
