PMAC/PMAC2 V1.17C Addendum I1011 Resolver Excitation Gain [New, Geo PMAC only] Range: 0 – 3 Units: Gain-1 Default: 0 I1011 specifies the gain of the AC excitation output created by the Geo PMAC for resolvers, with the gain equal to (I1011 + 1). With a gain of 1, the nominal AC output has peak voltages of +/- 2.5V. The following table lists the possible values of I1011 and the nominal output magnitudes they produce: I1011 is only used if the Geo PMAC’s Feedback Option 1 for analog position feedback is ordered. I1012 Resolver Excitation Frequency Divider [New, Geo PMAC only] Range: 0 – 3 Units: none Default:
0 I1012 specifies the frequency of the AC excitation output created by the Geo PMAC for resolvers as a function of the phase clock frequency set by I900 and I901. The following table lists the possible values of I1012 and the excitation frequencies they produce: I1012 is only used if the Geo PMAC’s Feedback Option 1 for analog position feedback is ordered. 10 V1.17C Firmware Version I1011 Excitation Mag. 0 +/-2.5V 1 +/-5.0V 2 +/-7.5V 3 +/-10.0V I1012 Excitation Freq. 0 PhaseFreq 1 PhaseFreq/2 2 PhaseFreq/4 3 PhaseFreq/6
