Trigger Signal Settings

The latch trigger can be selected from general-purpose inputs 5 to 7 or the encoder's phase-
Z signal. The functions of general-purpose signals 5 to 7 from the control I/O connector are set
with the Input Signal Selection 5 to 7 (3404 to 3406 hex). External latch input signals used by
Latches 1 and 2 are set with the Touch Probe Trigger Selection (3758 hex).
Bits 2 and 10 of the Touch probe function (60B8 hex) are used to specify weather to latch with
an external signal or the phase-Z signal.
