TL1 spindle RPM

Hi. Our TL1 has suddenly started running at exactly 80% spindle speed. Eg. Demand 1000 get 800. Any ideas?

Spindle speed override set to 80% maybe?

Thanks Jim but unfortunately not that simple.

spindle limited in settings?

Is G50 limiting the spindle speed?

yes that is maxium splindle command

I tried G50 S2000 no joy. I have been through all the settings in the book and changed a few relating to spindle speed still no joy. No matter what you ask for you alway get exactly 20% less.

Its driving me nuts. Im starting to think that it may be an amplifier frequency issue.

G97-G98 ALSO CONTROL SPINDLE SURFACE FOOTAGE.

gregoryblane G97S1000M03 in MDI gives me 800RPM (CSS off) even after turning off and clearing the memory. Manual mode also only gives me 800RPM.

what about a gear change? may not have gears I have tl1 belt drive
m41 low m42 high???
running out of ideas

I tried that too. It made no diference also tried belt compensation in parameters, no joy. Thanks for trying.
