Output Bit: This bit is set when the remaining distance to travel from the
last feed command is within the monitoring window (switching threshold)
range. If the motor does not remain within this ± switching threshold
range, or if a new feed command is detected, the output bit is turned off. If
00.00.0 is entered, the function is not active.
Switching Threshold: This value is used to establish a monitoring
window. The last progression is considered completed when the
remaining distance is less than the switching threshold. Depending on the
friction and external forces acting on the feed rolls, and depending on the
control loop parameter settings, a small untraveled distance remains at
the end of each progression. This distance does not accumulate for more
than one progression. If this remaining distance (position deviation) is
greater than the switching threshold that has been set, the feed angle
monitoring function (if activated in Parameter A116) reacts, or program
processing is stopped. The typical values for the switching threshold for
feed-to-length progressions are 0.05 to 0.5 IU (IU = mm).
When the stop function is executed, the “Position reached” message is no
longer referenced to the previously stipulated target position.
