Good afternoon everyone, and thank you ahead of time =)
I have a Mazak PFH - 5800 with Mazatrol 640M 80 tool unit cell, which is giving me fits. There is a persistent code, 304 (F104) ATC Arm Position Malfunction, that the operating manual describes as coming in when the ATC is stopped outside of its intended position and/or the cycle has not completed after +10 seconds from when the control anticipates. (This is in the error list on page 2-6)
There is a recovery procedure of course, which in quick steps involves Home 1, Machine menu, ATC Maint, MF1+ATC Ready, selecting locations and basically telling the ATC where it is again. I have performed this procedure a few times and the error remains after the cell attempts to start up again; it simply returns after about a minute. The thing which is weird is that I can jog it through a complete tool change cycle, CW or CCW, and it picks up its proper location at 65 and 180 degrees either way. I am confused: if the ATC drive encoder were incorrect, I should think it wouldn't give me the pink indications on the HMI when jogging through the rotations. I do not see anywhere that a door position switch could be located that might be causing it to think it were blocked (for the ATC door, not the operating door) and in the operating manual, no signal line is specified for error code 304 to be picked up by anything, which would make me think it *was* the encoder unless the ATC has like a cam sensor or something internally? Obviously something is telling it that the ATC isn't where it wants to be to remain safe, and it isn't allowing automatic operation out of an abundance of caution - I just can't imagine what that input might be from here.
Any thoughts are appreciated, and I hope your week has been and remains well all around. Cheers, Owl
