8.1

Vref offset adjustment (R18)

Using a voltmeter monitor the voltage at the junction of R12 and R16 or the Junction of R20

and R22 on the EVAL626PD board with respect to GND (CN1) when calibrating the offset.

8.2

Current scaling

When potentiometers R16 and R22 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 R16

and R22.
