PWM mode smoothstepper
« on: December 27, 2018, 10:56:36 PM »
Hi
I am using port1/14 to turn on the VFD and this works  fine but can't figure out how to vary the spindle speed the voltage from the board goes straight to 10 volts from zero and I can't vary the speed

I use M3 to start the spindle and that's ok but the "S" command for speed does nothing the out put voltage to the VFD remains at 10 volt ( full speed)

any ideas of where to look the smooth stepper mention PWM mode but I have not found any where to enable it
Regards Ray

Hi,
On the Configure/Plugins/ESS/Spindle tab check the box for PWM (and PID if you need it and have an index signal to make it work).
Specify port1 pin 14 on the Configure/Plugins/ESS/Output Signals tab.

Hi
Thank you very much
I had the spindle pop up box set as it came and it was a little small and covered the relay button  I was about to send you a screen shot as there was no button visible and found the problem

Thanks again I am back on track now thanks to you and your very quick reply I also looked at a YouTube clip and that was not the same I did not realize you could stretch the pop up box probably varies with screen resolution but it cut it out nicely and look normal

Well there is always some thing people who do not play with computers do not know what frustration is
