BTW if you consider this VFD, dont!
If you have massive noise problems, you've been warned.
Schaffner FN2060-16-06 mains filter will help a lot (my DAB! radio works now) and ferrite bead(donut shaped ring) on rs485 line will stop your screen from going wonky.

I recently spent two days trying to get RS485 working with this VFD before giving up. It appears to be simply reject any communication on that external port no matter what settings are made. My reports in this thread might be interesting, but there's nothing good:

I would suggest just using PWM control, takes about 10 minutes to set up. If only I had a time machine...
