Setting the Output Current

The output current on the DPC50501 is set by an onboard potentiometer.  This potentiometer deter-

mines the per phase peak output current of the driver.  The relationship between the output current 

and the potentiometer value is as follows:

Reducing Output Current

Reducing the output current is accomplished by setting switch 1 of the DIP switch to the ON position 

and occurs approximately 20mSec 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 resistor is paralleled with the current 

adjustment potentiometer.  This lowers the total resistance value, and thus lowers the per phase 

output current.

Determining Output Current

The output current for the motor used when microstepping is determined differently from that of a full/half 

step unipolar driver.  In the DPC50501, a sine/cosine output function is used in rotating the motor.  The 

output current for a given motor is determined by the motors current rating and the wiring configuration of 

the motor.  There is a current adjustment potentiometer used to set the output current of the DPC50501.  

This sets the peak output current of the sine/cosine waves.  The specified motor current (which is the 

unipolar value) is multiplied by a factor of 1.0, 1.4, or 2.0 depending on the motor configuration (series, 

half-coil, or parallel).
