W±5.5
Optional. Its meaning depends on parameter "K".
If "K" has been defined, it is a thread repair cycle. It indicates the angular spindle position
corresponding to the thread measuring point.
If parameter "K" has not been defined, it indicates the angular position of the spindle
corresponding to the thread's starting point. This allows making multi-entry threads without using
the parameter "V".
The following example shows how to make a 3-entry-point thread. To do that, 3 threading canned
cycles will be programmed with the same values except for "W".

V±5.5
Optional. It sets the desired number of thread entries.
If not programmed or defined with a 0 value, the thread will only have one entry.
M±5.5
It defines the thread pitch increment (positive M) or decrement (negative M) per spindle revolution.
This parameter is incompatible with parameter K (thread repair); therefore, if both parameters are
programmed together, the CNC will display the pertinent error message.
It must be borne in mind that is a thread pitch decrement is programmed and the pitch
reaches 0 before the end of the thread cutting operation, the CNC will display the
corresponding error message.
