Re: Spindle Voltage Output
So, that's not your video??
Need to see your Mach3 settings.
Re: Spindle Voltage Output
That is correct this is not my video. But I have the same settings that he is showing. I apologize if I was not suppose to link this video. What other settings in mach would you need to know.
Thanks

Re: Spindle Voltage Output
Here is what I have for the output
Attachment 405962
Re: Spindle Voltage Output
Sorry, I meant motor outputs, specifically for the spindle. I was going by memory, as I don't have Mach3 installed here.

No Problem. Here is the motor output

Re: Spindle Voltage Output
I made the changes to Mach3 and it seems that the output voltage is different. When I tell it to output 24,000 RPM it outputs 5 volts. When I tell it to output 12,000 RPM it outputs 3 volts. But the RPM do not change.

Re: Spindle Voltage Output
Now you getting a varying output which is a good start:)
Re: Spindle Voltage Output
Yes. I agree, but why would it be 5 and 3 volts instead of 10 and 5 volts for the above RPM.

Do you want 0-5V or 0-10V from you bob to your VFD...don't worry about the rpm not changing yet...we can sort that just now:)

Okay you just answered my question....you want 0-10V. Now i am not sure what bob you using, do you maybe have a selection on your bob for 0-5V / 0-10V??

I am pretty sure that it is a 0-10 volts because it was producing 7 volts.

True that makes sense....i need to know your other settings for the spindle

Re: Spindle Voltage Output
I used a relatively low pwm base frequency because i use a microcontroller to read this signal. You might use a higher frequency:)
........select minimum pwm as 0
basically use my settings as a starting point
Re: Spindle Voltage Output
What are your pulley speeds set to?

Max 24000, min 0, ratio 1

Re: Spindle Voltage Output
And if the voltage is changing, but the VFD is not, then you're VFD settings are wrong. Check PD001 and PD002. There's also a jumper that needs to be set correctly.

I have checked the PD settings. Where is this jumper located. Do you have a pic that might help.
