Hello,
I tend to think that the problem is in the indramat servo drive TRK 6-4U. At some (500,1100,1200,4000) selected spindle revolutions, no axis movement is performed. When observing the LEDs on the servo drive when the movements are disabled, the LED H2--> n ist (not)= n soll lights continuously. At most other spindle speeds, when the axis movements are working, the LED H2 goes out with a delay of about 1s when the spindle is started. For a while, we helped ourselves to make the feeds work by reducing the spindle speed to 85%, but now that doesn't help either. I noticed that capacitor C18 is completely black, which is not normal, so I preferred to remove it until the arrival of the other one. I tried setting the P1 trimmer on the first pcb, it would have been better, but it started stuttering at other spindle speeds as well.
I am attaching a few pictures and a table of measurements.
Has anyone had a similar problem or can someone help me solve this problem.
