Hello Hood,
well almost, I would say.
I turn on the frequency controller by hand. While running, the correct speed is displayed, but when i stop the spindle, run out of the spindle shows the last value to slow even at standstill. I hope you understand what I mean, my English is a little rusty. But Threading is always o.k. Only the continued displayed low Spindle Speed, for exampel 125 1/min is an irritation...at standstill.
Greetings, Tom

Did you tell Mach the spindle was stopped by calling M5 in code or MDI or by pressing the spindle button on the screen?

Tom I am just simulating here with the index pulse but if I command a spindle speed or press the spindle button the S True DRO shows the value equal to the pulses I am simulating. When I stop the spindle or command  a M5 the S True DRO returns to zero, so afraid I do not know why it does not do that for you.
Only thing I can think of is you are meaning the commanded spindle speed DRO is staying at the last commanded speed. If that is what you mean then that is normal and I think it has always been that way. If you want that to zero then you could alter the M5 macro to zero it.

Hello Hood,
at the DRO is the latest average of the last spindle rotation bevore stopping. You realize well, if the spindle rotates slowly by hand, changes the DRO accordingly, but never returns back to 0 at stopping.
It shows, as the DRO ist "waiting" on the next Index Impulse.
Not Nice, but threading works.

I dont know what to suggest, the DRO goes to zero for me (with your xml) if I tell Mach the spindle has switched off, ie press the button on screen to turn off, have code call a M5 or call a M5 from MDI.

Toms,
I would suggest you create a new xml.
I couldn't get my spindle rpm to display in the DRO no matter what was tried with your xml from reply #55.
