• By registering a measured value trigger within the "expectation

window" the value in parameter P-0-0224, Probe, number of marker

failures is cleared.

Note: The "expectation window" cannot be used with "time

measurement"!

The limitation values for the "expectation window" are set in the following

parameters:

• P-0-0204, Start position for active probe

• P-0-0205, End position for active probe

The "expectation window" has to cover a minimum range so that at least

on actual position value generation can take place within the window after

the probe signal edge has been detected:

In the case of modulo scaling of the position data, a maximum value for

the "expectation window" mustn’t be exceeded as otherwise it exceeds

the modulo value range and therefore is without effect:

Notes on Commissioning

Make the following settings in S-0-0169, Probe control parameter:

• evaluation of probe signal edge as measured value trigger

• select enabling mode of probe (single measurement or continuous

measurement)

Make further settings in P-0-0226, Probe, extended control word:

• activation of expectation window and failure monitor

• activation of time measurement

• probe selection

Select measuring signals from S-0-0428, Probe, IDN list signal

selection; enter the selected parameters in:

• S-0-0426, Signal select probe 1

• S-0-0427, Signal select probe 2
