Connecting 3rd party VFD with Masso

Hello everyone.... I am a newbie in the CNC field. I am assembling a CNC for my little applications. Unfortunately i bought a chinese VFD i. E. Yuanshin YX3000 for the spindle but i don't know how to connect it to Masso 3 axis controller as the manual is in chinese only. If someone can help me that would be great..

Hi Sourabh,

I did a quick search for your VFD and found this manual online. It is in English and I think it is the right one. If it is it should help you to get up and running.

The trick is to get the VFD running with switches for FRW and REV and a Variable Pot to control the speed.
  • The FWD switch should turn the VFD on in the Clockwise direction when it is closed and off when it is open
  • The REV switch should turn the VFD on in the Counter Clockwise direction when it is closed and off when it is open The Reverse is optional as most CNC routers don't run their spindles in reverse. i don't use it on mine so if you don't want reverse then forget this one.
  • The Variable POT will increase and decrease the spindle speed. This must be an external control and not the built in one if it has it.

Only after getting the VFD functioning in this way should to think about connecting it to the Masso and the good news is that it is easy.

The connection will be something similar to the one shown in the link below but get it running first and then we can look at connecting it.


hope this helps

Cheers

Peter

Curious... why wouldn't the built-in variable POT control the speed?

If you want Masso to control the spindle speed based on the G-code, then you can't also control it with the POT. Set P0.01 to 5

If you want to set the speed manually and just receive start and stop commands from Masso, then you leave the potentiometer in control.

Thanks for that explaination Jolbas!

Good question.

If you look at my VFD it has a built in POT which can be used to control the speed from the front panel. The problem with it is that you need to select different parameters within the VFD to make it work as well as shift a link on the circuit board. For example the internal POT uses 5 volts control signal and not 10 volts so there is parameter that needs to change or the speed is full speed when the POT is only half way turned. The upshot is that if you have it working with the internal pot and connect it to the Masso it would not control the speed.

By making sure that an external POT is used and works to control the speed when setting up the VFD then you can be sure that the Masso will work when it is connected. If it doesn't then you will know where to start looking when fault finding.
