Siemens Sinumerik 810T GA3 - HALT: EINLESEFREIGABE (STOP: READ-IN ENABLE)

[ili_gaydarski]

Hello friends!
There is a lathe with a Sinumerik 810T GA3 system. The machine was working fine. A notification appeared in Automatic mode HALT: EINLESEFREIGABE (STOP: READ-IN ENABLE) when I pressed the START button. Don't read the sentences now. Even without a sentence entered in MDI and AUTOMATIC, when I press the START button I have this alarm - only the door lock and light are activated. I am asking for advice! I checked the collet tightening - it works. I have the full documentation available. If anyone can read schematics I can send pictures. Please advise what can enable read ban. Thanks to all who can help!

We also had the same error. We identified the problem. The problem was that the spindle encoder belt broke.
