Hi,

we have a Mazak SQT 18 MS (Mazatrol T Plus control) in the shop. The last few days, the machine is not starting up in the morning.

After switching the cnc-control on, we are receiving an Emergency-Stop-Error (33) with addition of "SERVO".

Sometimes - after a few tries - the error is gone and the control and the machine will start up.

Once it is starting without the error, it will run for the rest of the day without a problem...?

We tried to remove and refit the bus-connection cables between the control-modules and that seemed to help for a few days, but then the error came back.

Any ideas? Thanks!
