If a different value is programmed for the VARI parameter, the cycle is aborted after output of
alarm 61002 "Machining type defined incorrectly".
NUMTH (number of thread turns)
Use the NUMTH parameter to define the number of thread turns with a multiple-turn thread.
For a single-turn thread, the parameter must be assigned zero or can be dropped completely
in the parameter list.
The thread turns are distributed equally over the circumference of the turned part; the first
thread turn is determined by the NSP parameter.
To produce a multiple-turn thread with an asymmetrical arrangement of the thread turns on
the circumference, the cycle for each thread turn must be called when programming the
appropriate starting point offset.
