6.4 6.4 DRF offset
Offset using the handwheel, DRF
In addition to all the translations described in this section, you can also define zero offsets
with the handwheel (DRF offset).
In the basic coordinate system, DRF offset affects geometry axes and special axes:

However, a handwheel assignment must be made for the machine axis (e.g., via "Activate
handwheel" NC/PLC interface signals), to which the geometry axis and special axis can be
mapped. You will find more information in the appropriate Operator's Guide.
Clear DRF offset, DRFOF
DRFOF clears the handwheel offset for all axes assigned to the channel. DRFOF is
programmed in a separate NC block.
