Not bad....

[potts43]

Just ran gcode from old test.
This did run but odd results.

There is no m3 or s commands in gcode.

Mdi - s0
Ext turned to 50%

Run gcode

Spindle turns on

Mach3 3 shows....

0 rpm
12000 s-ov
12000 spindle speed

Vfd - 380hz

This should be around 200hz


Edit.....reexamined gcode found

M03 and s12000

I am guessing that with the settings I've got s12000 does not = 50%

You cant ref your spindle on both the pot and mach3 at the same time.....

Do you have both the pot and mach3 wired to the VFD analog input??

I was told that was ok

I would not do it that way.....what are you trying to achieve?

Why not rather have remote/auto (mach3) and local/manual pot??

[potts43]

However....if I turn the pot to 0 and run the gcode the vfd stays at 0hz even though mach3 shows the gcode s speeds. It looks like the pot over rules mach3

I guess I was trying to use both to do the same job which isn't working.....

you can get the huanyang to display RPM. Program PD144=3000 and now it will display 0 to 24000 set the display for ROTT

[potts43]

Ok you are right.

I unwired the pot completely.
I ran it again and the speed changed to the gcode. I've worked out that s6700 is 200hz which I guess must be 12000rpm.

I guess I need to change the mach3 pulley ratio now so that when I type s12000 it equals 200hz. At the moment it reads 350hz.

A job for tomorrow.

I've tried changing pulley 1s ratio but that didn't seem to do much.....but if I Change the max speed to 44000 and run a s12000 command the Vfd shows 200hz.

This seems like a work around as surely it should be the ratio I need to alter?

Is there a parameter to allow the on board pot to work with mach3 in auto?
