1230 HEIDENHAIN Technical Manual iTNC 530 HSCI
Example of a <name>.H.AFC2.DEP file after a cut with active AFC:
Proceed as follows to select the <name>.H.AFC2.DEP file.
Select the Program Run, Full Sequence operating mode
Shift the soft-key row
Select the table of AFC settings with the SETTINGS TABLE soft key
Select the protocol file with the EVALUATE TABLE soft key
FMIN Mean value of the feed-rate minimum values during cutting in
%.
Based on the mean value you obtain a meaningful tendency for
F-min (tool wear), and not only an individual instantaneous
value.
PMAX Maximum recorded spindle power during machining. The TNC
shows the value as a percent of the spindle’s rated power.
PREF Reference load of the spindle. The TNC shows the value as a
percent of the spindle’s rated power.
OVLD Reaction by the iTNC to overload:
M: Perform an NC-function macro defined by the OEM
S: Immediately perform an NC stop
F: Perform an NC stop once the tool has retracted
E: Only display an error message on the screen
–: Do not perform an overload reaction
The iTNC conducts a shutdown response if the maximum
spindle power is exceeded for more than one second and at
the same time the feed rate falls below the minimum you
defined.
BLOCK Block number at which the machining cut begins.
