7. If you wish to teach the next intermediate position, repeat
the steps listed as from step 1.
Repetition accuracy The repetition accuracy when moving to the intermediate
positions depends on the type of drive and on the length of
the measuring system.
Detailed dimensions for repetition accuracy with the drive
you are using can be found in the drive-specific supplement.
Please note
Observe the following instructions in order to achieve
good positioning behaviour and the repetition accuracy
specified.
– The distance between the intermediate position and the
drive end position must be at least 10 % of the complete
cylinder stroke length or of the complete rotary angle, in
order to provide a sufficient compressed air cushion.
– Positioning paths between taught positions should not be
less than 3 % of the complete cylinder stroke length or of
the complete rotary angle.
With linear drives and cylinders the positioning paths
should be at least 20 mm.
– If the intermediate positions P.03 and P.04 lie at the same
point and if movement is made to one of the intermediate
positions (e.g. to P.03), only the output bit corresponding
to the order (e.g. O3) will be set when the intermediate
position is reached. The output bit of the other intermedi-
ate position will be set for 50 ms only if the position is
exceeded (overswing) (sensor function).
