Hello,
I have a 2.2kW water-cooled spindle + Huanyang VFD. Everything is setup and works fine when using the VFD front panel. Now I connected the VFD to my BOB in order to control it with Mach3, using this wiring diagram (which is correct, by the way ^^):
17713
I also changed the following settings:
PD001 = 1
PD002 = 1
PD070 = 1 (My VFD had it factory set to 0, thought the manual says that factory setting is 1... but oh well. This setting just tells the VFD that my BOB sends 0-10V and not 0-5V).
In Mach3, I activated the spindle and set it as shown in my now-famous-BOB's doc (https://www.google.be/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uact=8&ved=0ahUKEwiEo43u25LLAhUlG5oKHVnEAeEQFggcMAA&url=https%3A%2F%2Fwww.machsupport.com%2Fforum%2Fin dex.php%3Faction%3Ddlattach%3Btopic%3D29618.0%3Bat tach%3D40507&usg=AFQjCNH9X0BYQgc-jWmTqNv-W03KMGzhKw&sig2=tvzQWVwqXiOd1db9hJ2GKQ).
Works fine for controlling RUN/STOP from Mach3, but I can't control the spindle speed. Even stranger, the RUN/STOP buttons of the front panel are correctly disabled, but not the potentiometer. Therefore, I can still control the VFD frequency with the front VFD front panel's potentiometer. When I do so, the only, the VFD now allows me to press the STOP button, and then Mach3 loses track of the RUN/STOP state of the VFD.
I checked with a voltmeter the VFD input and my BOB sends the correct voltage for the speed I set in Mach3 (i.e with 3200RMP in Mach3, the BOB sends about (3200/24000)*10 = 1.3V, 5000RPM in Mach3 sends about 2V, 12000RMP gets 5V, etc). So, apparently, Mach3 is correctly set, and the BOB sends the right voltage. I checked the VFD manual and the way I wired the BOB is correct.
Remember, PD002 is set to 1, so the VFD should not let me use the frequency potentiometer on its front panel.
Thanks for your help.
All the best,
G.
