Hey Alan,
that is why you had no success with the wiring from Masso Documentation website I show in my Hitachi WJ200/Omron MX2 to Elite Masso wiring table. It needs to have “PLC” bridged to “P24”, not to “L”. Try it out, it will work very well. There is also a big hint to connect PLC to P24 on the image of the Masso Documentation website:
Image: Spindle VFD examples → Hitachi VFD – Masso Documentation
(It shows the Hitachi NE-S1, but the ports and their labels are identical with the Hitachi WJ200).
The wiring I show is with sinking inputs wiring and needs to have “PLC” bridged to “P24”.
The wiring you show is with sourcing inputs wiring and needs to have “PLC” bridged to “L”.
If you combine the wiring of the one with the bridge of the other, it can’t work, that is why I immediately asked you wether when testing my Hitachi WJ200/Omron MX2 to Elite Masso wiring table you followed the hint on the Masso Documentation image to connect “PLC” with “P24” (and not with “L”). I knew that if you omitted that step that would be the reason that it cannot work.
You see that the bridge (=“short bar”) with PLC is different on these two wirings?
