Good day,

I have added a second hand Hermle UWF 1000th into my machinery. Now I have the following problem:

 machine is started
 X, Y, Z reference points are approached
 When approaching the reference point on the y-axis, an external emergency stop is being triggered and the machine cannot proceed.
 If the machine is rebooted, the error occurs again.
 Within the start-up routine, the order of the axes was reversed as well. The problem again is the same (Y-axis).

My question now: what can be the cause of the error and how can I fix the problem.

Best regards
René
