My first Post in the wrong forum (but still relevant):
Hello, fellow machinists.
I have a 1991 Maho MH 800 C, and I'm having trouble getting it started. I've read through many of the posts and know of issues with starting the hydraulic pump motor. Here's my problem:
I turn on the main power to the machine. I then go to turn on the hydraulic pump, and it does not turn on. It will turn on while I depress the button, but it won't stay on.
I know of the process of starting the hydraulics: Press the button once, until the machine turns itself off, and then re-press the button and the Clear key to perform the final start-up. I've done this process over and over, but still the hydraulic motor won't stay on after the button is released.
Also, the drive which states the parameters (red button in middle with 4 arrow keys pointing the four directions) says, "No Power." I'm not sure why this is, since all has been wired seemingly correctly and done by a professional who doesn't know the problem, either.
Upon initial start-up, there's an Error 57 on the machine. I have read that this error means that a safety interlock is not engaged. I've checked all interlocks, and they're engaged. On the control, upon trying to start the machine, there are three errors: Error O23, M02, and I04.
Further, once the hydraulic start is pushed and the machine turns itself off, there's an Error 14 on the machine while I depress the button.
I do not have the error codes book--only the operator's and programming manuals, as well as a parts catalog and hydraulics/pneumatic schemes. I'm missing the electrical diagrams.
Any advice would be appreciated in this matter. I need to get this mill up and running.
Thank you.
Jack
Update:
I can now get the hydraulic pump to stay on for about 5 seconds. But after 5 seconds, it shuts off. On the machine, Error 05 or 14. (I don't know what these mean.) While the hydraulic pump is on, the drive which previously said "No Power" then says "Ref PT," which I know is the next step: to find the reference points in all the axis. But, of course, the drive returns to "No Power" once the pump is off.
The errors on the control are the same: O23, M02, I04.
Any help is appreciated.
