Hi Guys,

I'm trying to wire up a sunfar c300a VFD and not 100% sure on how to connect to the masso, I've attached the manual for the VFD, any help would be appreciated.

Thanks

Hi Reece

Before connecting your VFD to Masso you first need to make sure you have it running with external control.
  • You need to get it stopping and starting with the use of an external Forward switch.
  • If you plan on using reverse then you also need to get it working with the use of an external reverse switch. (Ignore if you don't plan on using reverse.)
  • Lastly you need to be able to set the speed using an external voltage. eg a 1.5 volt eg an AA battery will give you 15% of top speed or a 3 volt coin cell will give 30% top speed.

I apologize if it sounds like I am putting you off but it is important that the VFD be properly configured before you think about connecting it to Masso. You will only make troubleshooting 10 times more difficult by adding yet another piece of equipment into the equation if you don't have it working at the most basic level.

You may already have this working so please let us know and we can move onto the next step.

Cheers

Hi Peter,

Thanks for the quick reply, I'll have a play with it over the next couple of days and try to do as you suggested. I had it running off an external potentiometer prior to installing the masso and this is the last hurdle to getting the machine fully operational.

I'm sure I've got a few frustrating hours in my future trying to reconfigure the VFD's programming to cooperate.

I've had a look through all your wiring diagrams for common VFD's and am unsure about where to connect pin 4 and 6 of the masso as I can't see an equivalent of the DCM or digital frequency signal common on my VFD.

Thanks Reece

I thought @clover might have answered with a drawing by now. So, I'll try to explain what connections to make.

As your VFD shows in fig3.3 FWD & REV are controlled by switches to GND and in fig3.5 there is only one GND terminal and in the write up the various GND connections are stated to be common terminal, it can be safely assumed that all signal GNDs can be connected together.

So, using the Yuhuan Huanyang diagram as the basis for your connections.

MASSO VFD
  • 7 REV
  • 5 FWD
  • 6 GND
  • 4 GND
  • 1 VC
  • -ve GND

If FWD & REV don't work reverse the connections at the MASSO, as it not clear from a quick read of the manual the polarity of the FWD & REV pins, but as VS is positive, I think that the connections that I have listed are correct.

In regard to parameters to set I don't think you need to change any if you have had it running on an external pot.

Hope this has helped you.

Regards,

Arie.

Hi Arie,

Managed to get a chance to play with it today and your pin out was 100 percent correct. Only thing I haven't got working is the reverse direction, but forward is spot on. I don't really need reverse but if in future I do, i'll just have to mess around with the vfd parameters.

Thanks for the help guys, can finally start cutting! Cheers

Hi Reece

Glad you got it working. The fact you had it working with the Pot and switches means you were basically there and it was just a matter of connecting it which surprisingly, is the easy bit.

I did a drawing last night for when you got it working externally but Arie and yourself already had it working when I got Home from work.

I have attached it here for anyone who wishes to connect one in the future.



For the reverse issue I found 2 commands that might help.

If you have a look at the manual at page 41 /42 it says that the F0.5 needs to be set to 0 which is "Two-line mode 1" (Default)

This will give separate FWD and REV switches that will work with Masso according to the diagram in the manual page 42.
F0.5 Combination methods of running the command of terminals
0?Two-line mode 1
1?Two-line mode 2
2?Three-line mode

Also checkout F0.6 where reverse looks like it can be disabled.
F0.6 Steering control The first part of LED (form right to left):
0?Running direction is consistent with setting direction
1?Running direction is opposite to setting direction
The second part of LED?
0?Prevention REV is valid
1?Prevention REV is invalid
The third and fourth part of LED(form
right to left)?Reserved

Hope this helps.

Cheers

Peter

Hello,

I am having a similar issue. I also have a SUNFAR VFD controller except it is a E300 model. It is somewhat different than the c300a model mentioned above. Here is a link to the manual...

https://www.automationtechnologiesinc.com/wp-content/uploads/downloads/2012/05/VFD03.pdf



The VFD was configured for use with a Richauto controller that doesn't use 0-10v because the controller is not capable of doing so (a major reason in my choice of using MASSO for better control )

I will only be needing FWD (CW) direction for this spindle. It has already been configured for the 7hp liquid cooled spindle and can run it via the knob on the panel.

I tried to wire it up similarly to the VFD above (without reverse), but it didn't work.

Any help with be appreciated.

I already got the axis set up and running. Haven't done the rotary A axis (CNC router with rotary) but I am waiting on restoring the table before setting it up. So far, I really like the MASSO. Especially not having to deal with a PC.

Wire the same as Peter's drawing using the following pin arrangement
  • 5 -> X1
  • 7 -> X2
  • 1 -> A1
  • -ve -> CM

and set parameters to
  • F0.0 = 1
  • F0.2 = 1000
  • F1.7 = 4
  • F1.8 = 5
  • F1.9 = 0

This should get you started.

Regards,

Arie.

What about the FWD to CM (ground) as shown in the diagram?

I understand using the X1 and X2 for inputs (and using a common ground). I may try to swap the polarity on those tomorrow (as suggested by you earlier). Perhaps my model might need it.

Not needed, from manual

FWD-CM decides running direction when panel control mode. It s valid when close with CM terminal.

You are not running in panel mode.

Did you also connect MASSO pins 4 & 6 to CM? Need that to complete circuit!

I only did a quick read of the manual to find the info I pointed out, but you need to read the manual and check for any other parameters that might need to be changed to allow external control.

Have you looked at Peter's VFD video? In that he sets out steps to go through to connect to MASSO.

Regards,

Arie.

Arie,

I have watched the video a few times and still the same results. I can control the spindle currently, but I am forced to open the electrical panel and press "RUN" to turn on the drive first. Then I can send a M3 s12000 and it will go correctly. M5 will turn it off. I still cant figure out the on/off part using the masso switches (4,5 and 6,7). I just need CW as the spindle will never be in reverse direction. Current parameters are set as you requested earlier. By the video, when I measure voltage from CM terminal to x1, x2, x3, or FWD I get +9.0 volts.

Also, if I connect FWD to CM (all I need to do to control from panel knob) while using the masso 0-10v , then it switches the direction of the spindle even if not in "panel control mode" as the directions imply.

Wire using the following pin arrangement
  • 4 -> FWD
  • 1 -> A1
  • -ve -> CM

and set parameters to
  • F0.0 = 1
  • F0.2 = 1001 (different that C300 model!)



Drive starts up with Masso control when F0.2 is 1001 and FWD is connected to ground via PIN 4 on the Masso (using masso for ground switch). It works perfectly. I do not need reverse and didn't attempt to figure that one out.

Also, the e300 is kinda glitchy. When setting F0.2 to 1001, I found that I have to do this twice for some reason. It always goes back to 1000 on the first try. Perhaps a firmware or logic problem on the drive.

Hope that helps!

Dreyfus,

Easy MASSO pin 6 to X2 & pin 7 to "gnd"

I missed the 4th part of F0.2

Arie.
