I have a Dinosaur of a Swiss that I am trying to bring back to life.
It is a Citizen Cincom F12 with a Fanuc 3T control.
It is going to need a new VFD for the spindle, but at this point I am running into another problem.
I can jog the machine around fine with the joystick, but I have to overwrite the "RDYS" bit to "1" in diagnostics to to anything in MDI.
I went through the manual tracing the ladder logic, and it seems that bit "CNT" needs to = "1", leads to "CNTD" to = "1" for "RDYS" to ="1":
This is the rung that I am not understanding.
When I display the bits for "CNTS" & "TCNT" in diagnostics, they both read "1".
Shouldn't that cause the "CNT" bit to be "1"?
I tried manually writing the "CNT" bit to 1, but I am not able to like I am the "RDYS" bit.
Am I overlooking something in this ladder diagram?
