Good day.
Faced a problem. Error OL2 is not reset.
It occurs mainly at line starts at low speeds (due to the technological mode).
The problem is that the error is not reset by any method. But over time, it disappears itself. After that, the drive is functioning properly.
Contacted by manufacturers, no solution was found.
https://www.obsoleteindustrial.com/roundtable/index.php?topic=220.0 recommendations from this topic have been implemented.
We never found the electronic thermal relay, which is mentioned in the technical manual.
Has anyone encountered such problems, are there any solutions?
