3.2.3.12 Synchronised stretching/compression in Y direction
(
Stop!
l If input CDATA−X−RESET = 1, the stretching/compression factor must not be
changed. Otherwise the drive may lose the synchronicity.
l If the FB YSET1 is not used, then set C1313 = 0 (asynchronous
stretching/compression).
l Set C1295 = 1 for stretching/compression factors > 100 %.
This function is useful if more than 8 profiles are required for a lift changing process (Y axis) of the cam
drive. The lift can be changed online via stretching and compression. The function is only valid for
the cam drive, not for the master value.
Synchronised stretching/compression is required when the master value and the cam drive must run
absolutely synchronously and the factor must be changed during operation.

Fig. 3−13 Connection of the function blocks for the stretching/compression function in Y direction
The figure shows the minimum wiring. All function blocks used to generate the
stretching/compression factor must be entered into the processing table between the function
blocks CDATA and YSET1.
l The function is only active if C1313 = 1.
l The change−over between the stretching and compression factor is carried out during zero
crossing of the profile.
