12.1
Vref offset adjustment (R18)
Using a voltmeter monitor the voltage at the junction of R17 and R20 on the EVAL6235N
board with respect to GND (CN1) when calibrating the offset.
12.2
Current scaling
When potentiometer R22 is set full clockwise, a 100% current setting on the practiSPIN
software screen corresponds to a Vref of approximately 0.88 Vdc or a peak motor current of
about 4.4 A. The peak current can be set to a lower value by adjusting R22. The reference
voltage inputs can be monitored at the junction of R17 and R20.
