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.
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
Peter

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
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
