Hello,
I have been doing some searches to see if there was something obvious I am missing on 'Not Ready' condition of the machine, I have yet to find anything as it seems it is a generic condition of the machine. So I will try to include what machine I have, what I have tried and resources easily available.
1. This is the 80's era machine. I purchased it locally about 6 months ago, it was working (actually saw it running) at the shop I purchased it from. I was told he was using the drip feed option to program it although I have yet to find where that connected. The machine has Fanuc 6M - B controls. This machine has the 4 axis option.
I received with the machine the 'Operation Manaul' for the MillAC 4H as well as the 'Operation manual' and 'Service Manual' for the Fanuc 6M-B.
2. What I have looked at (and tried): So when I push 'on' on the Fanuc controls it turns on and once the screen clicks on it displays 'Not Ready' and a 'Ver' number. I do not know if it displays any messages during boot up prior to that screen as the CRT isn't on then. I then push 'Machine ready' button and nothing happens. At this time the machine has 3phase power, I have selected the 200-220 vac input switch in the main input cabinet as I measured the voltage into the machine at 213vac out of the transformer. However I do not have a phase rotation meter, so I do not know which order of wires are needed.
Also, I verified there is air pressure into the machine manual says 5-7kg/cm...I had to convert, so I need ~70-100psi. That at least runs into the regulator, can't say where it goes (or doesn't go) after that.
So at this point the machine has power, has air, the control cabinet fans are running, the CRT is on, and NO other lights are on.
My understanding is that at this point the hydraulic system would need to be started which is what I am assuming the 'Machine ready' button would do. the hydraulic system indicates it is half full of oil. The manual indicated there is not a level sensor.
I checked all of the E-stop buttons (the two I found) and they are out. The one on the controls cabinet I was able to visually check the contacts were moving.
I looked at the alarms in the Fanuc and there was none displayed
I looked at the diagnostics and confirmed that the switches seem to work: i.e. when I change from 'Tape' to 'remote' the bits toggle, when I spin the pulser remote the bits change. When I select an axis and set to 'jog' and press '-' the 'axis jog -' bit toggles.
So at this point I have been trying to figure out where the 'Machine ready' button goes. I do not have a maintenance manual for the MillAC 4H machine so I do not have a wiring diagram that shows where that button is wired to. I looked through the Fanuc manuals to try to locate it, but it doesn't appear to be tied to fanuc controller unless the name is different. There are connection diagrams in the Fanuc maintenance manual, and pages 193 and 194 show the ladder logic for the operators controls (single block, dry run, zero return, manual absolute, cycle start, feed hold...etc) but it does not show any button called 'machine ready'
The MillAC 4h manual says that for start up I 1. turn on the controller and 2. start the hydraulics (which I am assuming is the 'machine ready' button).
I have found nothing labeled 'hydraulics on' and the manual gives no button reference to find on a diagram.
At this point I am going to check the diagnostics to see if any of the axis limit switches are triggered. (in case that affects the e-stop circuit, but keep in mind I have no alarms).
The other thing I am going to start checking are the fuses.
Can anyone provide some more insight into the 'Machine Ready' button? Or any suggestions or pointing out things I have missed or misunderstood.
Thank you,
David
