Siemans Sinumerik 810 controller problem

Never seen one, never worked on one, but a pound to a penny says there is either a micro switch or proximity sensor used as feed back for the axis clamp to report it's status, and it's possibly out of adjustment, broken wire, or of course the input card that receives the signal may be faulty.

Thanks I thought the same, but cant seem to find anything. I will just have to wait and see what Siemens can find. I need to identify a "box of tricks", some sort of sequencer I think, any objection to me sending a photo or 2 to you direct ? Bob

Absolutely no problem Bob

I think these are a lant bed lathe?

This has probably got something to do with the brake on the X axis that stops it falling under its own weight when powered off.

Usually these brakes are integral with the servo motor.

Thanks Wayne We did take the cover off the servo, but didnt see anything obviously wrong, but we are no experts.......... Bob

We've only got two lathes left with Sinumeric controllers, one 2mx5m 30 tonne Ravensburg and one 5mx10m 80 tonne Waldrich Siegen one 810, upgraded last year to 840 and one 840, so not quite comparable any more.

All but 5 of our 15 Sinumeric controlled milling machines have gone, plus all the old AB faithfuls (B****y F*****g French). I can ask the Millwrights if the error rings a bell, but I suspect that Wayne might have got it.

Many thanks, and yes please. The Siemans website and help desk is an absolute nightmare. I have no objection paying a technician if only I could find one !!, until then, open to all suggestions (how do machines seem to "know" your busy and need the dam things to work, and not start acting up !! ) Bob
