Huanyang VFD 2,2kw Water Cooled Spindle to D3MB6HCv1 mainboard

@max3d Thanks for this. Can you explain a bit more about the red wire you have used? Is it just connecting DCM and FOR or is there something else there?

Many thanks,

Does the Duet3 PWM output need filtering to get an analogue signal for the VFD or will the Huanyang work from the PWM signal directly?

If the spindle controller needs an analog signal then you do need to convert it. In any case, I recommend using the converter because it provides optical isolation between the Duet and the spindle controller. However, instead of using an OUT pin to drive the converter, you could use the Laser/VFD output and set the jumper on the converter to 5V.

@dc42 Many thanks for the answer.
As it happens, I ended up making an opto-isolated board to drive my VFD (very similar to the Huanyang) with filtering for VFD speed and an Arduino to convert the VFD's tacho voltage to a variable frequency logic level signal that drives the Duet's Fan0 RPM input:

@mdhazell Greetings. Change PD001 from 0 to 1 to change spindle on/off from "operator" control to "external" control on the VFD control panel. You will need to power up the VFD manually before a job. I can see where this might cause some confusion because you can set the VFD up to power up and down automatically. The DCM and FOR terminals are used for that.

Good luck ...

@jay_s_uk Thanks for the reply. I did not have my email notification turned on so I missed your reply.

I used a converter to protect the mainboard. I followed a suggestion from one of the administrators from another post. At the time they did not have enough information on the Huanyang VFD and the converter would be an added safety measure.

Great addition to the post. If anyone wants to nix the converter they can use your method.

@max3d Thanks for this. So, you mention the red wire is a jumper between DCM and FOR, is it just used to connect the two together?
Thanks,
Mark

Max3D

@mdhazell Yup, you got it. The red wire connects the two terminals together.

To test the setup, enter M3 S500 on the DWC console to turn the spindle @ 500 RPM and all should be well. Enter M5 to turn it off.

But after installing the red wire jumper the spindle starts rotating after its powered and doesn't stop by M5 and looks , like doesn't want rotate slower than ~500rpm
Do I need to connect the second module to another port to control On/Off function?

I'm using Duet 3 MB6HC Firmware 3.4.1
Any help will be very appreciable !
