CN10, 11, 12 & 13 are for the I/O wiring. The I/O wiring is different for each application (welding, handling, general...) also if your robot came directly from Japan it has the default for that application. If it came from Motoman in Ohio it has a different configuration, if it came from Canada it will have a different configuration again.
Ok I understand it , but my robot is for welding application , now I must use for general application, if possible or not ?
and the output for welding now i can use for turn on a light and input for read a state of the external buttons ?
