Setting the Output Current
The output current on the MBC10SI1 is set by the on-board potentiometer R29 (Refer to Dimensions/
Jumper and Potentiometer Locations). This current adjust potentiometer determines the per phase peak
output current of the driver. This relationship between the output current and the potentiometer setting is
as follows:
Potentiometer SettingsReducing Output Current
Reducing the output current is accomplished automatically depending on the current reduction setting in
the SMPG-SMSI software. 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. This is done when the pulse generator is not running.
