Check whether the allocation of the end
positions to POS-MIN and POS-MAX via
the function TUNE-POS is correct.
If incorrect:
Execution TUNE-POS again.
If correct:
TUNE-POS with this arrangement of the
end positions is not possible since they
are too close together.
To determine POS-MIN and POS-MAX,
move the actuator in each case in the
direction shown on the display.
