3. Push the hardware limit switch for the
relevant end position in the direction of
the switching cam until it responds.
4. Fasten the hardware limit switch directly
at that point.
5. Repeat the last 4 points in the other end
position.
6. Push the slide into the end positions.
You can then check whether the hardware limit switches function correctly and
you can make sure that the switching cams are seated without play.
7. Fasten the safety limit switches between the relevant mechanical end position
(W) and the nearby hardware limit switch (H).
The following specifications apply here:
A braking path of length n remains between the response point of the hard
ware limit switch (H) and the response point of the safety limit switch (S).
The response ranges of the safety limit switch and the hardware limit switch
overlap slightly. When switching on the axis you can thereby avoid unde
fined operating states.
In spite of the fact that the defined end position S is overrun, the safety
limit switches remain actuated until the mechanical end position (W) is
reached.
