Checking the axis positions
Refer to your machine manual.
This function must be adapted by your machine
manufacturer.
After switch-on, the control checks whether the position of an axis
matches the position directly after shutdown. If a deviation occurs or
functional safety (FS) detects that a change has been made, this axis
is marked on the position display. The control displays a red warning
triangle in the status display.
Axes that are marked can no longer be moved while the door is
opened. In such cases you must approach a test position for the
axes in question.
Proceed as follows:
Select
Manual operation

Press the
MOVE TO INSPECTION POSITION

Press the
SELECT AXIS
soft key
Select the desired axis by soft key, if required.
Or press the

soft key
Press the
NC start
key
The axis moves to the test position.
After the test position has been reached, the control issues a
message.

on the machine operating panel
The control displays the axis as a tested axis.
Repeat this procedure for all axes that you want to move to the
test position
NOTICE
Danger of collision!
The control does not automatically check whether collisions
can occur between the tool and the workpiece. Incorrect pre-
positioning or insufficient spacing between components can lead
to a risk of collision while approaching the test positions.
If necessary, move to a safe position before approaching the
test positions
Watch out for possible collisions
Refer to your machine manual.
The location of the test position is specified by your
machine tool builder.
