Actual value:
The current position coordinate (actual position value) of the selected axis is displayed.
The value is displayed in the appropriate dimension.
Distance to go:
This displays the difference between the actual position value and the target coordinate.
This only applies to modes "AUTOMATIC" and "AUTOMATIC S1 NGLE STATEMENT","1 N-
Aux. function:
function is displayed as a numerical value. The auxiliary function (M function) M02 is the
default.
Reference point:
This field shows whether the reference point is "set" or "cleared" (not set).
Synchronization:
The possible displays here are "yes" or "no". Synchronization yes means that the reference
point is determined by the negative edge of the reference signal and the excitation pattern
counter equals O. Otherwise, the reference point is only determined by the negative edge.
Teach-in mode:
This displays whether the selected axis is in teach-in ("on") or not ("off").
Status of axis:
Here, the status of the axis is displayed. Possible displays are "finished" and "running".
If there are no correct machine data for the axis on the module, then no actual value and no dis-
tance to go will be displayed. The statuses reference point, synchronization, teach-in mode and
axis status remain unchanged. Without machine data, only mode 17 (clear error) can be ex-
ecuted apart from input and output of data.
Description of the input fields for changing modes
The inversely displayed input fields are only completed after pressing function key <Fl >
(MODE). If you press cF1 >, the display changes to the change mode function.
Note
The displayed values, actual value (actual position value), distance to go, auxili-
ary function and the displayed axis attributes (=> Section 2.7 "Axis Attributes"),
are then no longer updated.
The function key cF1 > changes to "ACTUAL VALUES", the function key <F7> changes to
"HELP". By pressing <Fl > (ACTUAL VALUES) you return to the actual value display mode.
