QS
parameters (the S stands for string) are also available on the
control and enable you to process texts.
Q parameter
type Q parameter range Meaning
QS parameters: Parameters affect all NC programs in the control’s memory
0 – 99 Parameters for the user , where no overlaps with the
HEIDENHAIN SL cycles are present
100 – 199 Parameters for special functions on the control that can be read
by NC programs of the user or by cycles
200 – 1199 Parameters primarily used for HEIDENHAIN cycles
1200 – 1399 Parameters that are primarily used with manufacturer cycles when
values are given back to the user program
1400 – 1599 Parameters primarily used as input parameters for manufacturer
cycles
1600 – 1999 Parameters for users
NOTICE
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.
