300103 O Constant cutting cross-section
300104 I Constant cutting cross-section
If a different value is programmed for the VARI parameter, the cycle is aborted after output of
alarm 61002 "Machining type defined incorrectly".
_VRT (variable retraction path)
The retraction path can be programmed on the basis of the initial thread diameter in the
_VRT parameter. For _VRT = 0 (parameter not programmed), the retraction path is 1 mm.
The retraction path is always measured according to the programmed system of units, inch
or metric.
PSYS (the last parameter displayed on the screen)
This parameter specifies the selection of longitudinal thread, face thread or taper thread.
Figure 2-8 0 = longitudinal thread
