Hey Brenden,

I don’t have a photo documentation (although planned), but here you can see the WJ200-specific pins that you have to use:

| Internal Masso  
Spindle Control  
Interface | Function | GX12 6-pin connector  
on back of Elite Masso G3 Touch (internal wire colors) | Wire color and pin on | | VFDs  
 Hitachi&nbsp;WJ200  
or Omron&nbsp;MX2 |
| --- | --- | --- | --- | --- | --- |
| G1 or G2 or G3 or G4 or G5 | GND | pin&nbsp;1 black | pin&nbsp;1 black | goes&nbsp;to | "L" |
| SC1 | 0-10 V Analog | pin&nbsp;2 red | pin&nbsp;2 red | goes&nbsp;to | "O" |
| SC5 | CW | pin&nbsp;3 yellow | pin&nbsp;3 yellow | goes&nbsp;to | 

“1 (FWD)”  
_(with C001 set to “00”)_

 |
| SC4 & SC 6 | Common | pin&nbsp;4 green | pin&nbsp;4 white | goes&nbsp;to | 

“L”

 |
| Not connected | | pin&nbsp;5 white | | | |
| SC7 | CCW | pin 6&nbsp;blue | pin&nbsp;5 green | goes&nbsp;to | 

“2 (REV)”  
_(with C002 set to “01”)_

⚠ **Important: The short bar must be on “P24” and “PLC”, not on “L”!** (image on the left is correct).

On WJ200 settings, there also must be:  
A001 (source of motor speed command) set to “01” (analog input) and  
A002 (source of run command) set to “01” (control terminals).

All this applies to both Hitachi WJ200 and Omron MX2.
