Spindle speed control, Huanyang VFD and DC-03
I have been trying all sorts of combinations to get my Huanyang VFD, the Spindle and a DC-03 card working as they should. I am beginning to doubt my ability to do even such a simple thing as set up this system to work properly even when I am given step-by-step instructions and pictures to follow as well.
I have included pictures of all the current setup and it is (supposedly) the correct way to do things but I just cannot get even a peep out of the system.
The first picture (P1010638) is showing the DC-03 board and the connections to the VFD
The brown lead is from DC-03 AV+ to ACM on the VFD
The blue lead is from DC-03 Vout to Vi on the VFD
The green and yellow lead is from DC-03 AGnd to 10V on the VFD
The second picture (P1010640) is a better view of the DC-03 board and the colours of the connections to the BOB can be clearly seen.
The third picture (P1010641) is the BOB which is a c10 and here it can be seen that I have wired the connections from the DC-03 correctly
Still on picture number three, the red wire is the 5 volt DC input to the C10 board. The (green/yellow) earth is on the logical ground next to pin 17. Pin 17 is the (blue) signal pin to the DC-03 and the last two leads (the brown and white wires to input pins 1 and 16) are the leads to the DC-03 onboard relays that determine direction. These are not yet being used.
The next three photos show that the pins on Mach3 are correctly set up for the motor outputs, Output signals and the spindle.
Finally, the last photo shows that I have set the speed of the spindle to 20000rpm and that the spindle is currently turned off. Clicking on the "Spindle CW F5" button will cause the LED above the button to start flashing yellow but no speed will be shown
You will just have to take my word for it that I have also set the VFD up so that it will take external commands by putting a 1 in PD001 and PD002. I also tried a 0 in PD001 but that didn't work either. All the other PD commands were als entered as per Mike's instructions.
All the above was taken from the excellent manual written by seafurymike and Peter Homann has confirmed that these settings are correct.
SO WHY THE HELL DOESN"T IT WORK THEN?
Anomalies:
With all wires connected then the most I can get as a reading is 0.68 v between any connection.
If I disconnect the wire from AV+ (on the DC-3) to the ACM on the VFD, then I get a reading of 10.12 volts on the VFD between ACM and 10V and also between ACM and Vi
If I disconnect all wires from the DC-03, I then get 10.12 volts between 10V and Vi and also between 10v and ACM but nothing between Vi and ACM
There is a jumper next to the 10V connector on the VFD. It is labeled VI / VR. I have no idea what it is for because it is not mentioned in the manual.
