EVAL6208PD board configuration
11.1
Vref offset adjustment (R18)
Using a voltmeter monitor the voltage at the VrefA or VrefB test point on the EVAL6208PD
board with respect to GND (CN1) when calibrating the offset.
11.2
Current scaling
When potentiometers R8 and R17 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 4.4 A. The peak current can be set to a lower value by adjusting R15
and R18. The reference voltage inputs can be monitored at the VrefA or VrefB test point.
