Explanation
Depth infeed rate
Feedrate
Maximum depth infeed
Machining type
UNITS: Infeed type
1 = Vertically with G1
3 = Oscillating
HUNDRED: Reserved
Reserved
Geometrical mode
UNITS: Reserved
TENS: Reserved
HUNDRED: Select machining or just calculate start point
0 = Compatibility mode
1 = Normal machining
THOUSANDS: Dimensioning of reference point, slot length
0 = Center
1 = Inner left-hand +L
2 = Inner right-hand -L
3 = Left-hand edge +L
4 = Right-hand edge -L
Display mode
UNITS: Machining plane G17/18/19
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
HUNDREDS: Reserved
THOUSANDS: Software version identification
1 = Functional extension LONGHOLE (dimensioning of reference point)
Alternative mode
UNITS: Final depth Z1 (abs/inc)
0 = Compatibility
1 = Z1 (inc)
2 = Z1 (abs)
