Description:
Manually clears the hardware latch for the encoders fast position input. This is used when the
FASTAUXLATCHMODE keyword is set to 2 so that further fast latches are disabled until re-enabled by the
user.
The state of the latch can be read using
FASTAUXLATCH. This indicates if an axis has had a position
latch occur. Reading
FASTAUXLATCH will clear the software status of the latch but this does not re-
enable the hardware latch. Writing to
FASTAUXENABLE also clears the software latch.
To clear the latch, a value of 0 must be written.

Description:
The
FASTAUXLATCH keyword is used to determine if an axis has had a fast position latch occur since
the last time that
FASTAUXLATCH was read. Reading this keyword also clears the software latch.
The mode of fast latching is set with the
FASTAUXLATCHMODE keyword. If mode 2 is used, then the
FASTAUXENABLE keyword must be used to clear the hardware latch.
