Geo MACRO Drive User and Reference Manual
Geo Macro Drive MI-Variable Reference 153
MS{anynode}, MI932 Resolver Excitation Frequency Divider
Range: 0 – 3
Units: none
Default: 0
MI932 specifies the frequency of the AC excitation output created by the Geo MACRO for resolvers as a
function of the phase clock frequency set by I7m00 and I7m01. The following table lists the possible
values of MI932 and the excitation frequencies they produce:
MI932 Excitation Freq.
0 PhaseFreq
1 PhaseFreq/2
2 PhaseFreq/4
3 PhaseFreq/6
MS{anynode}, MI933 SSI Clock Frequency Divider
Range: 0 – 3
Units: none
Default: 0
MI933 specifies the frequency of the digital clock output for the SSI-encoder interface. The following
table lists the possible values of MI933 and the clock frequencies they produce:
MI933 SSI Clock Freq.
0 153.6 kHz
1 307.2 kHz
2 614.4 kHz
3 1.2288 MHz
MS{anynode},MI934-MI939 (Reserved for future use)
Range: 0
Units: none
Default: 0
MS{anynode}, MI940 Resolver Excitation Gain
Range: 0 – 3
Units: Gain-1
Default: 0
MI940 specifies the gain of the AC excitation output created by the Geo MACRO for resolvers, with the
gain equal to (MI940 - 1). With a gain of 1, the nominal AC output has peak voltages of +/-2.5V. The
following table lists the possible values of MI940 and the nominal output magnitudes they produce:
MI940 Excitation Gain
0 +/-2.5V
1 +/-5.0V
2 +/-7.5V
3 +/-10.0V
