Hello

CnC and Mach3 newbie here.
I am contrlling my spindle with the 0-10 Volt signal.
When I try to turn on my spindle either in mach3 oder with gcode the system stop with the error: PWM Bumped to minium setting.

If someone could have a look at my xml and maybe point a if there is any bad settings it would help me a lot.

Thanks in advance.

you will have to select a pin and port (Spindle step output) for your PWM output you are using.

but PWM is not a 0-10V signal.

The output should be defined.
As far as I know my hardware should output a 0-10 Volt PWM signal to the frequency converter.
But I am no expert and could be wrong.

I retried a couple of times today with the documentation of the hardware and kinda got it working.
Got a new issue, but it has nothing to do with what I posted.

Thanks for your reply and help. :-)

some more informations about your hardware and some photos would be helpfull.

a PWM signal is not 0-10V. PWM is allways a signal witch goes low and high (high normaly 5V),
only the relation between low and high (pulselength) defines the change.

I managed to generate this message today.
I have just finished setting up the router again after a year in storage and a cross country move.
This is a PMDX system,
PMDX-126 Breakout Board w/PMDX-107 Isolated Speed Controller and an ESS.
I am controlling a HY02D223B TY I VFD.
I have tested the spindle run/direction and rpm previously with no problems.

I was using one of the wizards to generate some g-code, the message appeared when I attempted to run the program.
I don't recall which one, no sense going there.
It shouldn't really matter as machine related action should be managed by the Mach 3 settings.

but PWM is not a 0-10V signal

I will have to disagree with that statement.

With the vfd being used  uses 0-10 volts at a given frequency  to control spindle rpm if the correct parameters are set in the vfd.

fyi:

Yea you are controlling voltage by controlling the on time compared to the off time thus creating a voltage value form 0 max voltage making a digital signal analog.

"Base frequency" if too high means you cannot run the at a lower speed (RPM) than allowed.
Spindle will be bumped  to run at a higher RPM than your g-code S settings. So the message is just informational.
By setting my "Base frequency" to 33Hz and I can make my WATER-COOLED spindle to run at 1000 RPM minimum. But Air-cooled spindle must be restricted to a min RPM of 8,000
