General Description
The DPE25601 is a single-axis 2.5A bipolar microstep driver/controller, containing 2 Kbytes of 
nonvolatile stored programming space, quadrature encoder feedback, and a 24W power supply, 
all  enclosed  in  a  package.    It  provides  flexible,  independent  control  of  bipolar  stepper  motors 
with a current range from 0.5 to 2.5 amp/phase with a microstepping resolution of 1,600 steps 
per revolution from a computer or any machine controller with a serial port.  It is also...

Motor Selection
The DPE25601 incorporates a Bipolar Microstep Driver that is compatible with both Bipolar and 
Unipolar Motor Configurations, (i.e. 8 and 4 lead motors, and 6 lead center tapped motors).
Step motors with low current ratings and high inductance will perform better at low speeds, pro-
viding higher low-end torque.  Motors with high current ratings and low inductance will perform 
better at higher speeds, providing more high-end torque.
Since the DPE25601 is a constant current source, it...

Reducing Output Current
Reducing the output current is accomplished by setting switch 1 of the DIP switch to the ON posi-
tion and occurs approximately 1 second after the last positive going edge of the step clock input.  
The amount of current per phase in the reduction mode is approximately 50% of the set current.  
When the current reduction circuit is activated, the current reduction r\
esistor is paralleled with 
the current adjustment potentiometer.  This lowers the total resistance value, and...

4 Lead Motors
Multiply the specified series motor current by 1.4 to determine the current adjustment potenti-
ometer value.  4 lead motors are usually rated with their appropriate series current, as opposed 
to the Phase Current, which is the rating for 6 and 8 lead motors.
8 Lead Motors
Series Connection:  When configuring the motor windings in series, use the per phase (or uni-
polar) current rating to determine the current setting potentiometer va\
lue.
Parallel Connection:  When configuring the...

Methods of Communication
There are two methods for sending commands to the DPE25601.  One is to directly talk to the 
DPE25601 by using Direct Talk Mode.  This is usually used with a computer or PLC (Programmable 
Logic Controller), where the computer or PLC gives the DPE25601 serial commands to off-load its 
processor.  For example: A PLC can utilize its outputs to toggle the DPE25601’s inputs and gain con-
trol of variable speeds, variable programs, variable distances, etc.  Simply using the...
