Programming Manual, 03/2013, 6FC5398-2BP40-3BA1
Explanation
Contour approach movement (not vertical approach/retract)
UNITS:
1 = Straight line
2 = Quarter-circle
3 = Semi-circle
TENS:
0 = Last movement, in the plane
1 = Last movement, spatial
Retract path or retract radius (inc, to be entered without sign)
Reserved
Chamfer width (inc)
Insertion depth (tool tip) on chamfering (abs/inc), see _AMODE
Mode for evaluation of programmed geometrical data
UNITS: Reserved
TENS: Reserved
HUNDREDS: Select machining/only calculation of start point
0 = Compatibility mode
1 = Normal machining
Display mode
UNITS: Machining plane G17/G18/G19
0 = Compatibility, the plane 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)
TENS: Type of feedrate: G group (G94/G95) for surface and depth feedrate
0 = Compatibility mode
1 = G code as before cycle call. G94/G95 same for surface and depth feedrate
THOUSANDS:
0 = Compatibility mode: contour name is present in _KNAME
1 = Contour name is programmed in CYCLE62 and transferred to _SC_CONT_NAME
Alternative mode
UNITS: End point Z1 (_DP)
0 = Absolute (compatibility mode)
1 = Incremental
TENS: Units for plane infeed
0 = mm/inch
1 = Reserved
HUNDREDS: Insertion depth for chamfering (_ZFS)
0 = Absolute
1 = Incremental
