Function
The DRF (Differential Resolver Function) offset allows an additional
incremental zero offset to be set using the handwheel. "DRF" is an
axial procedure which acts on the basic coordinate system.
Handwheel selection is permissible via the axial interface only; i.e.
you can only use machine axes.
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).
Operating sequence
"AUTO" mode is selected in the "Machine" operating area.
The standard axis assignment is defined.
Enter the handwheel of your choice or select via the MCP.
Enter the increment size of your choice or select via the MCP.
VAR
The window "DRF offset" 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".
