Programming Manual, 02/2011, 6FC5398-2BP40-1BA0
Explanation
Milling direction
0 = Climbing
1 = Conventional
4 = Conventional + climbing (combined roughing + finishing)
Retraction distance before thread milling (inc)
Drilling feedrate (mm/min or in/min or mm/rev)
Drilling feedrate for remaining drilling depth (mm/min or mm/rev)
Feedrate for thread milling (mm/min or mm/tooth)
Finishing feedrate for CDIR=4 (mm/min or mm/tooth)
Evaluation of feed rates
UNITS: Drilling feed F1
TENS: Drilling feed rate for remaining drilling depth FR
HUNDREDS: Feedrate for thread milling F2
THOUSANDS: Finishing feed rate FS
String as marker for pitch input (for the interface only)
String for thread table ("", "ISO", "BSW", "BSP", "UNC") (for the interface only)
String for selection from thread table (e.g. "M 10", "M 12", ...) (for the interface only)
Geometrical mode, reserved
Display mode
UNITS: Machining plane G17/18/19
0 = Compatibility, the level effective before cycle call remains active
1 = G17 (only active in the cycle)
2 = G18 (only active in the cycle)
3 = G19 (only active in the cycle)
Alternative mode
UNITS: Drilling depth = Final drilling depth Z1 abs/inc
0 = Absolute
1 = Incremental
TENS: Amount/percentage DF for each additional infeed (degression)
0 = Amount
1 = Percentage (0.001 up to 100 %)
