Resolution Steps Rev Select2 Select3 Select 4 Table 7 SW1 Switch Settings L010197 January 2013 Setting the Output Current The output current on the MBC05641 is set by an onboard potentiometer This potentiometer determines the per phase peak output current of the driver The relationship between the output current and the po tentiometer value is as follows Peak Current Potentiometer Setting Peak Current Potentiometer Setting 100 eA Table 8 Output Current POT Settings Refer to Table 6 for specific motor current settings Reducing Output Current Reducing the output current is accomplished by setting switch 1 of the DIP switch to the ON position and occurs approximately 1sec after the last positive going edge of the step clock input The amount of cur rent 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 Determine 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 MBC05641 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 adjustmen
