Deleting curve data
If bit 6 is set in Z122.2– the curve data is deleted. Since parameter Z122.2– can only be
written if the drive is disabled, the polynomial curve can only be deleted in this state.
4.8.13.3 Changing the chaining sequence
The sequence of the single segments can be changed during operation. Two parameters
(
Z122.6– and Z122.41–) are available for this. Based on an example this procedure is
to be explained.
It is assumed that there are five curve segments on the drive controller. Segment 1 is to
be defined as the starting segment. The specified chaining is only processing three seg
-
ments currently - these segments are shown in the following table.
The segments 4 and 5 are not active at the current chaining. These shall be connected
as an alternative path to segment 2.
The parameters Z122.6– and Z122.41– are written to as follows:
P122.6 = 0x00010004 and P122.41 = 0x00050003 (see description of Z122.6– and
Z122.41–)
After initiating the chaining change by bit 5 in the control word Z108.1– the sequence is
as follows:
The active curve now consists of four segments. Segment 2 was removed from process-
ing and the segments 4 and 5 are now actively processed.
