10.13 Multiple feedrate values in one block

Display
The contents of the active system variables are visible on the screen under
<OFFSET PARAM> -> "Setting data" ">" "Times/counters":
Total parts= $AC_TOTAL_PARTS
Required parts= $AC_REQUIRED_PARTS
Number of parts =$AC_ACTUAL_PARTS, $AC_SPECIAL_PARTS not available for display
"Number of parts" is also visible in the AUTOMATIC mode in the "Position" operating area in
the information line.
10.13 Multiple feedrate values in one block
Function
The "Several feedrates in one block" function can be used independent of external analog
and/or digital inputs to activate
● Different feedrates of an NC block,
● dwell time, and
● Retraction
in synchronism with the movement.
The hardware input signals are combined in one input byte.

FMA and F value
The axial feedrate (FMA value) or path feedrate (F value) corresponds to 100% feedrate.
You can use this function to realize feedrates that are smaller than or equal to the axial
feedrate or the path feedrate.

In addition to the path feed, you can program up to 2
further feedrates in the block; non-modal
Dwell time (for grinding technology: sparking-out time);
non-modal
Return path; non modal. The unit for the retraction path
refers to the current valid unit of measurement (mm or
inch).
In addition to the path feed, you can program up to 2
further feedrates per axis in the block; non modal
Axial dwell time (for grinding technology: sparking-out
time); non-modal
Axial return path; non-modal
