Hello everyone,
our mill machine is a HAAS TM-1. We replaced the battery about one month after the alarm LOW BATTERY VOLTAGE initially appeared. Since then, at powering up the alarm is gone BUT we cannot navigate through the control. Screen is frozen.

Searching through the Haas Electrical Service Manual (https://diy.haascnc.com/sites/defaul...df?0=%253F2123) we found out that our BBU-RAM is possibly corrupted and we have to clear it in order to unfreeze control. The steps to do this are written in the manual as follows (page 30-31):

Clearing the BBU-RAM
1. Type in "M3000D6C 300FFFF" and press Enter. The control responds with “Memory Test Passed” written several times. The command “M3000D6C” checks and clears just a portion of the BBU-RAM. It avoids the section that contains the serial number of the machine (Setting 26). Most problems can be solved without removing the serial number.

2. ...

Here is the part where we need help:

In the photos attached you can see the Main Processor Memory Map of our HAAS TM-1. As you see, memory address for BBU-RAM is $0600_0000 - $07ff_ffff.
I would like to ask IF we need to modify command "M3000D6C 300FFFF" provided in the Haas Electrical Service Manual to what is suitable for our machine's BBU-RAM address, in order to clear the BBU_RAM portion that does not erase machine's serial number.

Any help on how to do this would be appreciated, given that we work in a university lab and we have no money for a service tech.

Thank you in advance
George

I would not do any additional steps to clear the BBU Ram yet.

When your battery died, the machine lost all of its stored parameters. Most likely, you need to initialize the machine and reload the parameters as shipped.
There are many recent threads about this subject along with procedures on how to restore the machine, so do a search and you should find the answers you need.

Good luck!

Dear haastec,
thank you for your reply.

Before posting this thread I've searched and found numerous similar threads.
However, most of them answer on how to reinitialize a machine whose control is active
(e.g. http://www.cnczone.com/forums/haas-m...alization.html ).

Our problem is that TM-1 powers up until main control screen (see attached photo) giving us "PROG INTEGRITY ERROR" alarm and everything freezes at that point. Keys beep when pressed but there is absolutely no response.
Reading this thread (http://www.cnczone.com/forums/haas-m...-software.html mainly in posts #10 and #11) in combination with Haas Electrical Service Manual led us to our estimation that clearing BBU-RAM will help unfreeze the main screen.

If our estimation is correct, I have to stick on my initial question
OTHERWISE an advice on how to get our machine's control unstuck in order to proceed to its re-initialization would be more than welcome.
