Function
DRF is an axial technique that acts in the basis coordinate system. It
is only permissible to select the handwheel via the axial interface – i.e.
only machine axis names may be used.
The DRF offset can be switched on and off for specific channels by
means of the "Program control" function.
It remains stored until
• Power ON is performed for all axes
• DRFOF (selection of DRF via part program)
• PRESETON (modification of the actual value through Preset)
You can alter the DRF offset by traversing the appropriate machine
axis using the handwheel (the actual value display does not change).
Sequence of operations
"AUTO" mode is selected in the "Machine" operating area. The
standard axis assignment is defined.
Enter the desired handwheel or select via the MCP.
Enter the desired increment or select via the MCP.
VAR
The "DRF offset" window is displayed.
Traverse the required axes using the handwheel.
Using the same operating sequence, you can also return the DRF
offset to the value "0".
