Programming Q Parameters | Principle and overview of functions
QS parameters (the
S stands for string) are also available on the
control and enable you to process texts.
Q parameter Q parameter range
type
QS parameters:
0 – 99
100 – 199
200 – 1199
1200 – 1399
1400 – 1599
1600 – 1999
Danger of collision!
Q parameters are used in the HEIDENHAIN cycles, in machine
tool builder cycles, and in supplier functions. You can also
program Q parameters within the NC program. If, when using Q
parameters, the recommended Q parameter ranges are not used
exclusively, then this can lead to overlapping (reciprocal effects)
and thus cause undesired behavior. Danger of collision during
machining!
Only use Q parameter ranges recommended by
HEIDENHAIN.
Comply with the documentation from HEIDENHAIN, the
machine tool builder, and suppliers.
