I have a problem and I hope you can help me.
I am using delta SA2 PLC. I am generating a pulse train with DDRVA and sending it to a servo drive. Servo motor does not move correctly.
I took an oscilloscope and watched the signals coming form Y0 (only forward direction from DDRVA) and when counting the signals I saw that the first signal was not correct. (time of the signal was off and it had no "valley"). Other signals were within specified parameters.
The corrupt signal directly correlates to my positional error measured by the drives resolver.
I am using frequencies above 6 HZ.
Do you have a solution for this problem?
