Warning
Incorrect parameters can damage the fixed stops and the
drive.
Be very careful when setting the parameters.
When parameters are modified, the saved end positions and
adaptation values are deleted for safety reasons. Therefore,
the “teach” procedure must then be carried out again. Inter-
mediate positions already “taught” are retained.
All parameters are set to 0 at the factory. Further information
on the parameters see “Drive-Specific Supplement” for the
drive used.
Cushioning stage The cushioning stage serves to optimise the approach
behaviour when moving to the end positions (lower stage =
less cushioning).
Setting Description
Too high The positioning procedure is heavily cushioned.
The positioning time is extended.
Too low Leads to heavy overswing and, as a result, to hard
striking of the fixed stops.
Optimal The braking phase (counter pressurisation) is
started early enough. Less shaking when moving to
end positions.
Amplification stage The amplification stage should not normally be modified
(lower stage = less amplification).
