Dear Experts
We have a HMC
Even in MDI, when spindle is commanded to run at say 1500 rpm, then spindle is stopped via M05, again commanded to run at same or differnet RPM upto 5000 then we observe that every time spindle stops and starts, momentarily, spindle load shoots up even upto 204% - which we feel is inappropriate although we are aware of the fact load wud increase every time spindle is commanded to run and also when it is commanded to stop due to braking current
Request your opinion on to this although no Fanuc errors are generated
Regards
This would be a question for the machine builder. It may be normal. Have you just noticed this and maybe it has been doing it all along - or is it something new? The spindle acceleration parameters may be set too aggressively - or maybe that is how the builder wants it. Again, it would be best to contact your machine builder.
Thanks for your response. We would connect with OEM and share feedback in this forum
