Technical requirements
To be able to use the handwheel superimposition function,
HEIDENHAIN recommends the use of the HR 520 handwheel (see
"Traversing with electronic handwheels" on page 570). Direct selection
of the virtual tool axis is possible with the HR 520.
In principle, you can then use the HR 410 handwheel, but your
machine tool builder must then assign a function key of the handwheel
to selection of the virtual tool axis and program it in his PLC program.
The global program settings function is a software
option and must be enabled by your machine tool builder.
The machine tool builder can provide functions with which
you can set and reset global program settings under
program control, e.g. M functions or manufacturer cycles.
You can use the Q-parameter function to query the status
of the global program settings GS (see "FN 18: SYS-
DATUM READ: Read system data" page 342 ff).
To be able to use all functions without limits, the following
machine parameters must be set:
 MP7641, bit 4 = 1:
Permit selection of the virtual axis on the HR 420
 MP7503 = 1:
Traverse in active tool-axis direction is active in the
Manual Operation mode and during a program
interruption
 MP7682, bit 9 = 1:
Automatic transfer of the tilt status from the automatic
mode to the Move axes during a program
interruption
function
 MP7682, bit 10 = 1:
Permit 3-D compensation with active tilted working
plane and active M128 (TCPM)
