7-11 Touch Probe Function (Latch Function)

The touch probe (latch) function latches the position actual value when an external latch input signal or
the external encoder's phase-Z signal turns ON. G5-series Servo Drives can latch two positions.

The latch trigger can be selected from general-purpose inputs 5 to 7 or the external 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.
