6.1
Vref offset adjustment (R18)
Using a voltmeter monitor the voltage at jumper JP4 or JP5 the EVAL6205N board with
respect to GND (CN1) when calibrating the offset.
6.2
Current scaling
When potentiometers R17 and R21 are 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 2.64 A.
The peak current can be set to a lower value by adjusting R17 and R21. The reference
voltage inputs can be monitored at JP4 and JP5.
