Spindle up to speed confirmation

[bhdavis]

Is there a SPINDLE UP TO SPEED confirmation feature in UCCNC?

Up to now I've just been adding a P4 dwell command in my code to give time for the spindle to come up to speed. I believe some control packages have a way to confirm the spindle is up to speed before proceeding. Is that the case with UCCNC?

Thanks,

There's a delay after spindle start in UCCNC, which basically does the same thing as your dwell. But there's no built in functionality to wait for a signal from the VFD before continuing.

There is a wait for spindle function in the UCCNC 1.2117 which waits for the spindle to reach the programmed velocity, but for that you need an Index sensor or an encoder which measures the spindle speed.

I use a modified M3 macro. I get the actual speed from my vfd and compare it to the set speed when the speed is reached then the machine will move. Works great.

You should have an option for an input from the VFD.
