l Function block interconnection
The figure shows the minimum interconnection. All function blocks used to generate a
stretching/compression factor must be entered into the processing table between the function
blocks DCATA and YSET1.

l Activate function
The function is only active if C1317 = 1.
The changeover between stretching and compressiong factor is carried out during zero crossing of
the profile.
Change of direction
This function is only available for the internal X integrator (C1332 = 0).
“Direction” indicates the increase of the integrator (output -XPOS).
With positive input values at -DFIN the integrator runs from 0 to length X-cycle.
With negative input values at -DFIN the integrator runs from length X-cycle to 0.
The direction can be reversed under code C1314.
Input-XOFFSisnotinvolved.
Output of other status signals
Use of function block CDATA with relative data model
l The actual profile section is indicated through the assigned digital output CDATA-SEC1 to 5.
l The lengths of the single sections are output at CDATA-LEN1 to 5 in X direction. If they are
added they result in CDATA-ACTLEN. The actual length of a master value cycle is output at
CDATA-ACTLEN (code C1315/X).
l CDATA-BUSY-LENx = High
Outputs CDATA-LENx and CDATA-Y-END are being updated (important for cam profile
processing).
l CDATA-ACTCAM
CDATA-ACTCAM indicates which profile is being processed.
l CDATA-X0
Output CDATA-X0 indicates a zero crossing of the master value. The window width for the
comparison is determined via code C1309. The window is placed symmetrically around the
effective zero of the master value.
CW/CCW rotation
l CW rotation
In CW direction, the profiles are processed in ascending order.
If the last profile is reached, the process starts again at the first profile.
