SINUMERIK 840D/840Di/810D Programming Guide Cycles (PGZ) – 11.02 Edition
Retraction plane (absolute)
Reference plane (absolute)
Safety distance (enter without sign)
Final drilling depth (absolute)
Final drilling depth relative to reference plane (enter without sign)
Dwell time at thread depth
SW 6.2 or higher: Always operative now if >0 is programmed
Value range: 0<=DTB
Direction of rotation for retraction
Values: 0 (automatic reversal of direction of rotation)
3 or 4 (for M3 or M4)
Direction of rotation after end of cycle
Values: 3, 4 or 5 (for M3, M4 or M5)
Tapping with/without encoder
Values: 0 = with encoder, without dwell time (SW 6.2 or higher)
1 = without encoder, first programs the cycle, then the feed (SW
6.2 or higher)
11 = without encoder, calculates the feed in the cycle (SW 6.2 or
higher)
20 = with encoder, with dwell time (SW 6.2 or higher)
Thread pitch as thread size
Value range: 3 (for M3) ... 48 (for M48)
Thread pitch as value
Value range: 0.001 ... 2000.000mm
SW 6.2 or higher:
If _PTAB=0 or 1: in mm (as earlier SW versions)
If _PTAB=2 in thread starts per inch
Tool axis:
Values: 1 = 1st geometry axis
2 = 2nd geometry axis
or else 3rd geometry axis
Evaluation of thread pitch PIT
Values: 0...according to programmed system of units inch/metric
1...pitch in mm
2...pitch in thread starts per inch
3...pitch in inches/revolution
