Hello all,
Trying to troubleshoot our lathe. It will drop out on the 1000 Emergency Stop fault. Tracked it down to the K1 ready relay on the spindle drive. It is in the same circuit as the e-stop. Question is does anyone know what conditions the K1 relay is looking at to say it is good to go? I have checked the tachometer brushes and two of the accessible brushes on the Siemens spindle motor. All still have plenty of brush left.
The last time the drive faulted out we were fitting the part rotating the spindle by hand in spindle free mode when it dropped out. This got me thinking possibly something related to the spindle encoder?
Has anyone had a similar experience?
Thanks, Dave
