Note
Block−shaped acceleration profiles (without smoothing) cause high peaks in the
drive force, which can result in drive overload. In addition, through overswing
effects, positions outside the permissible range can occur. A smoothed acceler
ation specification reduces vibrations in the overall system and has a positive
effect on the mechanical equipment load.
S Check which regulator settings can be adjusted (e.g. smoothing, flattening of
the acceleration profile).
Positioning the limit switches
1. First push the cantilever arm into a mechanical end position (W) è Fig. 30.
2. Then position the slide at the distance h (safety distance) from the mechanical
end position (h = n + r) è Fig. 25.

3. Push the hardware limit switch for the
relevant end position in the direction of
the switching lug up to its switching
point.
4. Fasten the hardware limit switch exactly
at this point.
5. Repeat the last four points in the other
end position.
6. Push the slide into the end positions.
You can thus check whether the hardware limit switches function correctly and
whether the switching lug is seated free of play.
7. Fasten the safety limit switches between the relevant mechanical end position
(W) and the nearby hardware limit switch (H).
