Technical prerequisites
The global program settings function is a software
option and must be enabled by your machine tool builder.
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 444). 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.
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 operating mode and during a program
interruption
MP7682, bit 9 = 1:
Automatically transfer the tilted condition from the
automatic mode to the Manual mode
MP7682, bit 10 = 1:
Permit 3-D compensation with active tilted working
plane and active M128 (TCPM)
