348 HEIDENHAIN Technical Manual MANUALplus 620
Reaction to
change
(behavior)
The following reactions can occur when machine parameters are changed
using the config editor:
Change at any time
(NOTHING)
Program run is locked
(RUN)
PLC program prevents changes during program run
(PLC/RUN)
Allowed in strobe
(SYNC)
Move to ref. point
(REF)
Shut down control
(RESET)
Restart control
(REBOOT)
The abbreviated form of the detailed description for each parameter in this
manual includes the reactions that occur for each machine parameter.
Reaction NOTHING
Machine parameters with this reaction can be changed at any time, including
during program run.
Reaction RUN
Changes are only possible during a PLC strobe or NC stop.
Reaction PLC/RUN:
If machine parameters are changed while NN_GenCycleAfterReConfig is
set, the PLC program is recompiled. Changes to parameters are prevented in
any case while the NC program is running. In this case, the control issues the
error message Parameter change during program run, even if the reaction of
the parameter is NOTHING. Therefore, for parameters with the behavior
NOTHING, the text PLC/Pgm. run is locked is displayed in the config editor
to indicate the changed behavior.
Reaction SYNC:
Basically, the same characteristics apply as for the RUN reaction. In addition,
machine parameters with this reaction can, for example, be loaded from the
NC program by means of an MP subfile if a strobe with synchronization of the
advance calculation (SYNC_CALC) is pending. The parameter cannot be
activated through the PLC or the config editor during program run.
Reaction REF
After a machine parameter to which the REF reaction is assigned has been
changed, the affected axis is set to unreferenced.
A new reference run must be made for this axis.
Data objects with this reaction must not be changed during program run.
