Measured value output when probing
Parameter P96 allows you to activate measured value output when
probing with the KT edge finder. The edge finder is connected to D-sub
input X10.
Whenever the Probe Edge function is used, your display unit outputs
the position of the edge in the selected axis and the actual positions of
the other axes over the TXD line of the RS-232-C/V.24 interface.
Whenever the Probe Midpoint function is used, your display unit
outputs the calculated midpoint in the selected axis and the actual
positions of the other axes.
Measured value output with CTRL B is inhibited when a probing
function is active.
