“ instabilities” in function CTBL

In the process of work, we found
out that there are “ instabilities” in function CTBL.
Out of 12 comparisons, the first one and the last one(most frequently) do not function (sometimes but not always!!!) .

I changed the “min Cycle Time” to 20 ms and the dysfunction happens less frequently but still it happens sometimes.

Why do the dysfunction happen and what is its nature?

If I did everything correct or I should have done something else?

What else can I do?

I use: CPM 2A
Encoder 1000 pulse/rev

I would be very grateful for your help.

What is your developer version of CX-Programmer or else ?
Have you used INI(--), it depends of control data value ?
Is that encoder correct, wiring contacts etc.

I can't really help you, but...maybe Jay Anthony can help.

What are the DM values of DM 19-36? Your program only sets DM0-DM18, but you are using 12 comparisons.
