Mitsubishi FR-D720S-100 + Chinese 2,2kW spindle

Trying to connect Mitsubishi FR-D720S-100 frequency converter to chinese 2,2kW spindle. Where should pins 2 and 3 from Masso spindle connector be connected? I saw the wiring diagram of the inverter.

Also, what parameters should I set in the inverter to make it work?

I can manage the spindle from the inverter, but not from Masso. I just get intermittent flashing in the spindle output line between Low and High.

Many thanks in advance.

Pins 2 & 3 are not connected. Leave vacant.

Parameters to set are in the manual that comes with the inverter.

Arie.

Maybe anyone already made such VFD and spindle pair? Your help would be much appreciated

Don't own a Mitsubishi VFD so downloaded manual for it and just had a quick look and I could see from the index that sections 6.15 & 6.17 need to be read to set the VFD for 0-10v input and external control.

You need to get to know your VFD, so that you can fault find it, and the only way is to read the manual!! I know it's 512 pages.

Arie.

Did you get the vfd working? I have a fr-d720 as well. I got a potentiometer working to turn on the spindle but a no go on the fwd/rev switches.
