Skip the GX12-6P connector and go direct?

Hey Alan,

@Alphonse

@Aiph5u, yes I do think it would be helpful to have a simpler table for direct connection.

even if it’s just connecting the first column to the last column and ignoring all columns between in my table, I see that I should provide an additional table for direct wiring for each of the different VFDs for which I already made a connection table.

@Alphonse

Ref. G3 ground - There are several ground pins available on the Masso G3 controller. Wouldn’t G5 work? It is adjacent to the spindle control terminals.

According the Masso Documentation, the multiple Ground terminals are all the same. Of course you can use G5 instead of G3.

INFORMATION: There are multiple Power (Red-colored) and Ground (Black-colored) provided on the controller and can be used to easily wire drives, sensors and switches.

@Alphonse

BTW, I need to figure out what wire #S2 connected to the Masso G3’s “Spindle Output” control terminal in the Onefinity wiring scheme is for.

This wire does not connect to the GX12 connector but runs from the bottom of the Masso Touch where the power is connected from the Onefinity power supply/relay controller. I suspect it may be a trigger wire for the router control relay in the power supply.

The outputs CW (FWD) and CCW (REV) come in two different types: First as TTL-level outputs which have a high or low voltage depending on the logical state (1 or 0), and secondly they are available as terminals of a optocoupler. This is similar to a open collector output, that provide no voltage, the voltage comes from the VFD here, that is why the latter are used to go to the VFD.

Was this helpful from someone who never had a Masso G3 in hands and will never buy one ?
