The trigger is armed when the position capture register is read. After this, as soon as the GEO MACRO
Station sees that the specified input lines are in the specified states, the trigger will occur -- it is level-
trigger, not edge-triggered.
MS{node},MI913 Primary Encoder Capture n Flag Select Control
Range: 0 - 3
Units: 0 = HMFLn (Home Flag n)
1 = PLIMn (Positive End Limit Flag n)
2 = MLIMn (Negative End Limit Flag n)
3 = USERn (User Flag n)
Default: 0
This parameter determines which of the “Flag” inputs will be used for position capture (if one is used --
see MI912):
This parameter is typically set to 0 or 3, because in actual use, the LIMn flags create other effects that
usually interfere with what is trying to be accomplished by the position capture. If you wish to capture on
the LIMn flags, you probably will want to disable their normal functions with Ixx25, or use a channel n
where none of the flags is used for the normal axis functions.
MS{node},MI914 Primary Encoder n Gated Index Select
Range: 0 - 1
Units: none
0 = Use ungated index for encoder position capture
1 = Use index gated by quadrature channels for position capture
Default: 0
When MI914 is set to 0, the index channel input (CHCn) for the encoder mapped to the specified GEO
MACRO Node is passed directly into the position capture circuitry.
