EVAL6206N board configuration
7.1
Vref offset adjustment (R18)
Using a voltmeter monitor the voltage at jumper JP6 or JP7 the EVAL6206N board with
respect to GND (CN1) when calibrating the offset.
7.2
Current scaling
When potentiometers R20 and R26 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 JP6 and JP7.
