Power Brick Controller User Manual

Resolver Absolute Power-On Position

With resolvers, the absolute position is computed directly from the upper 16 bits of the AtanSumOfSqr
register. It is set up using the following key structure elements:
➢
Motor[].pAbsPos = PowerBrick[0].Chan[2].AtanSumOfSqr.a
➢
Motor[].AbsPosSf = Motor[].PosSf
➢
Motor[].ApsPosFormat = $00001010 (Upper 16 bits)
➢
Motor[].HomeOffset = user desired home offset value
Note
Connections and Software Setup
With resolvers, it is not recommended to use PowerOnMode (value
of 2) for power-on absolute position read. Instead, it is
recommended to issue a HOMEZ command from an initialization
PLC.
