    Default Frustrated with Mori SV500 spindle unlocking on M00

    I have 2 1998 mori seiki sv500s made within a month of each other. I have a haimler taster as tool #1 for setting work offsets. I use it to adjust offsets on every part sometimes. following will be some code as an example.
    The first mill will run this fine. It stops at M00, I hit offset button, change the offset, hit the mem button, hit the green button and away we go. Tool #1 is labeled a sensor tool in the control.
    If the sensor tool rotates for any reason, it will alarm. The 1st mill locks the spindle the whole time. The second mill unlocks the spindle on M00 and then sets a sensor rotate alarm. Is there a parameter to keep the spindle locked at M00?
    The control is fanuc 18ima.

    One of your machines must have a parameter set differently then the other. An easy thing to discover and fix yourself. If I were you I'd try this.

    Get yourself a text file comparison tool. There are free ones out there online. I use one called WinMerge. It's really great and super easy to use. Just drag and drop the two text (parameter) files you want to compare onto the desktop icon and it will open and show you the files side by side and highlight all the things that are different.

    So get your two text files of the machine parameters and compare them to each other. Have your parameter book handy, and explore each parameter difference by referencing what is said in the parameter manual. It will likely be obvious when you run across the offending incorrectly set parameter. If you don't have a parameter manual, every one of them can easily be found on the internet and downloaded.

    I bet you'll have it figured out in less then a half hour, as it doesn't take long to run through a set a parameters. Be sure to record your changes in case your first try doesn't work.

    Good luck.

    Hey Quarter Mile, thinking this through further I realize it's very possible that the parameter change you need is one of the ones supplied by the MTB. I'm not sure how to offload the MTB parameters, keep relays and the rest. Maybe you do. If nothing else you can still compare one machine to the other with the MTB parameter/ladder/relay book in hand.

    Update: Here are some settings in my SV-50 of late 90's vintage with 18M. YOURS MAY BE DIFFERENT!

    Keep Relay K2.3 - M0DEN
    1: When given an M0 command, orientation is executed without checking the distribution - complete signal.
    01: When given an M0 command, orientation is executed after checking the distribution - complete signal.

    Keep Relay K3.6 - SENORT
    1: Orientation can be commanded in case of sensor tool.
    0: Orientation can not be commanded in case of sensor tool.

    Keep Relay K5.1 - ORRST
    1: Spindle orientation command is not canceled by rest.
    0: Spindle orientation command is canceled by rest.

    Data Table D4632.3 - ORTREL
    1: Orientation is released when tool is unclamped.
    0: Orientation is not released when tool is unclamped.

    Change at your own risk!

    Hi Gentlegiant. I have compared the 2 parameter lists and I was unable to locate anything that was obvious. I've never done anything with the ladder before. I believe that's where I need to be. I have had a quick look and I haven't a clue where to start. Any suggestions for a tutorial on how to read this stuff?

    Hi 1/4 mile,

    The keep relay and data setting are in the PMC section of the machine. Hit SYSTEM / PMC / PMCPRM to get you to the right screens. FYI, the password for the ladder is normally the letter "L". You may have to go to the setting screen like you would when changing normal parameters and change the 0 to 1 to allow parameter changes. I'm sure I've changed some of these before, but also seem to remember trying to change something and having the control not allow it. You're on your own here as I'm at the limit of my knowledge about this section of the control. Whatever you do, I would make sure the NAME of the parameter matches what I wrote above more so then its actual address. (Although if I remember right, the NAME may not be present on the screen. Not sure.) You'll have to be the judge of how and what you want to change. You're working at your own risk. First I would just compare machines and see if one is set differently then the other along with what I wrote above. I hope you have a ladder book with the MTB PMC settings listed towards the rear of the manual. That would really help you to be certain of what you're doing. Good luck.

    Hi Gentlegiant
    I never mentioned in the 1st post that the door unlocks at M00 as well as the spindle releasing. The door and spindle does not unlock on the other machine.
    I found the following in the electrical circuit diagram manual. D461.1 MOULK. K5.1 ORRST. However D461.1 its not showing on the control. See attached images. Is there another place in the control I'm not finding? I also found K5.1 and it is the same (0) on both machines.

    Hi 1/4 Mile,

    Wow... I'm totally jealous of your color monitor and memory card port. I have the MSC 518 control, or something like that. My monitor is dark, monochromatic, and sad comparatively. Even your book looks to be in better shape.

    I think you're in the right place, and I have also had the same problem of something showing up in the book and not being found on the screen. Very frustrating. Still you should be able to make a direct comparison across your two machines and see if one has one thing set and the other doesn't. At least in the areas that you can see.


    You might want to waltz over to the PM forum and show/ask your questions there. On PM there are a couple guys that know everything there is about Fanuc, and have a good handle on Mori too. I'm also interested in finding the whereabouts of hidden Data Tables and Keep Relays. And also how to change the ones I mentioned that the machine wouldn't let me change.

    Like I said earlier, I'm about at the limit of my knowledge in this part of the control.

    I need to study up on if I can swap out for a color monitor!

    Thank You Gentlegiant. You got me looking in the right area, me thinks. I have not found 1 setting between the 2 controls that differ as of yet. Thanks again.
