PMAC 2 Software Reference
PMAC I-Variable Specification 161
I1013 Motors to Check
Temperature
0 Neither
1 Motor 1 only
2 Motor 2 only
3 Motors 1 & 2
If the Geo PMAC is checking temperature for the motor, the motor thermal sensor must be
connected to pin 23 of the main encoder connector for the motor.
I1015 SSI Clock Frequency Control {New, Geo PMAC only}
Range
0 – 3
Units
none
Default
0
Remarks
I1015 specifies the frequency of the digital clock output for the SSI-encoder interfaces on
the Geop PMAC. The following table lists the possible values of I1015 and the clock
frequencies they produce:
I1015 SSI Clock Freq.
0 153.6 kHz
1 307.2 kHz
2 614.4 kHz
3 1.2288 MHz
I1015 is only used if the Geo PMAC’s Feedback Option 2 for absolute position feedback is
ordered.
I1016 SSI Channel 1 Mode Control {Geo PMAC only}
Range
0 – 3
Units
None
Default
3
Remarks
I1016 specifies the mode for interpreting data from the first SSI-encoder interface on a
Geo PMAC. The following table lists the possible values of I1016 and the data formats
they cause the Geo PMAC to expect:
I1016 SSI Clock Freq.
0 (Reserved)
1 (Reserved)
2 Numeric binary
3 Gray code
I1016 is only used if the Geo PMAC’s Feedback Option 2 for absolute position feedback is
ordered.
