Q parameters with special functions
The TNC uses some Q parameters, for example, to exchange
coordinates between the datum table or the integrated PLC and the
program.
Q parameters for the datum table: Q81 to Q84
The TNC exchanges coordinates between the datum table and the
machining program with the following Q parameters:
Data
Parameter value
Return jump to the main program,
for example, from the subprogram.
Q153 = 0
Time exceeded during eroding and
Cycle 17 DISK cancelled.
Q153 = 1
