N0VUSUN and Mitsubishi-D700-SC

Ok well you have the Nvem S-axis wired up so were are you running those wires.?


I've never used either of these but I've wired many others controllers and VFD's and they all pretty much work the same.
Here's where I think they should go after looking at both manuals.

S-axis /Gnd1 goes to terminal 5 on Vfd which is Analog Gdn
S-axis/VSO goes to terminal 2 on VFD which is 0-10V.

This is your 0-10V speed reference voltage. Terminal 10 on the VFD is a 10V speed reference voltage in case if you wanted to use a potentiometer (POT) and would go to the wiper of the POT. In this case you don't need it because the Nvem supplys the 0-10V

S-axis/Out1 goes to STF on VFD (forward rotation)
S-axis/Out2 goes to STR on VFD (Reverse rotation)

However this would mean you have to tie the VFD control logic Gnd which is Terminal PC on the VFD to the same supply Gnd that the Nvem uses and this would need to be 24Vdc because that's what the VFD requires.


Or if your using a lower voltage say 12V to run the Nvem then you would need to connect the Out1 and Out2 to relays which use 12V coils and then put the STF and STR thru the relay contacts and back to PC on the VFD.

All your basicly doing is using Outputs 1 & 2 on the Nvem to turn on/off the RUN signal on the VFD by shorting STF/STR to PC(Gnd).

Then it's just a case of setting up the Outputs for Forward/Rev and Pulley speeds in Mach3 which the manual should tell you how.

Hope this helps.
