I have a MHI lathe that the battery went dead and im tring to get it going again. I have all the steps to do so but when i get to the format part in the data I/O erase screen it doesn't let me even curser over to type in format. It gives me a data protecting alarm. I have found edit lock C and B both are off.
I have been told that edit lock A is on witch should be a key switch but there isn't one on the machine. I have also talked to Mit. and they have told me I can change Y238 bit to 0 and that should do it but it won't (or I don't know the proper way to change it) let me do that either. please help
You can change Y238 to 0 through the PLC I/F page. Under DEVICE type the address (Y238), under DATA type 0, and under MODE type 2 and then try to format. Do not power off and on before formatting as this will change Y238 back to a 1.
Yo!
I'm in the EXACT same boat as you, on a MTC10-B lathe. Did you ever figure out how to get through this hurdle? I've talked to Mitz, went step by step through their process, only to be met with the same "DATA PROTECTING" alarm. Kinda sucks sack because the machine is super nice with parameters mostly intact as the only alarms are Z56 FIX_P REENTRY and Z70 ABS ERROR being displayed.
PLEASE,
If anyone can point me in the right direction it would be greatly appreciated. This is an outstanding piece of equipment that I am not able to utilize because of this issue. These are the only two alarms showing, and it appears that all of the parameters are actually still intact; based on the paperwork with the machine.
I have suddenly the same message on screen. Cannot edit program, nor create new program. Machine was/is running, making same part it was making before the error showed up, holding same tolerance. The key lock in front on control makes no difference whther it is in off or on position. ALmost to end of this run, will need to program new part soon. Any ideas?
