Hi all, has anyone ever come across a Fuling BZD312 inverter? I am try to find a manual for it but cant find it anywhere on the web, can find manuals for 200 and 300 series but they are not right for my unit, different connections and box etc

I am in the process of installing a new control card and have hit a wall.
My contact in China has advised to connect the vfd as follows


2. VFD connect Mach3 card:
1) FWD of VFD connect FWD of Mach3
2) ACM of VFD connect DCM of Mach3
3) Servo of VFD connect servo of Mach3
4) AR of VFD connect AVR of Mach3
5) need to change the parameter from F 0.03 to 2


The problem is there is no Servo or AR connection on the VFD and no servo on the control card
I thought maybe Servo is 10v? and AR should be RI? on the VFD. I have attached a photo of the vfd connections.
If anyone has any ideas that would be great, I know most of you will advise purchasing a better vfd and controller, but I would like to nut this out if I can
