Q parameters for texts
QS parameters (S stands for string) are also available and enable
you to process texts on the control.
Q parameter type Q parameter range Meaning
QS parameters: Parameters affect all NC programs in the control’s memory
0to99 Parameters for the user, where no overlaps with the
HEIDENHAIN SL cycles are present
These parameters have a local effect within macros and
OEM cycles. This means that changes are not returned
to the NC program.
For this reason, use the QS parameter range 200 to 499
for OEM cycles!
100to199 Parameters for special functions on the control that can be read by
NC programs of the user or by cycles
200to1199 Parameters primarily used for HEIDENHAIN cycles
1200to1399 Parameters primarily used for OEM cycles
1400to1999 Parameters for users
