Your machine must have absolute encoders to get those alarms. There is a procedure in the Mori maintenance manual that involves lining up plates with arrows on them (usually red arrows).
There should also be a battery on the alpha drives (which sounds like the one you checked). This battery is for the absolute encoder. There is also a set of batteries usually installed in a black box held closed by 2 flat head screws mounted on the electrical cabinet door. These batteries ("d" cell) are for the system memory (parameters, tool offsets, part programs, etc.). Do not remove either battery with the power off.
If you need more info on the zero return procedure for absolute encoders, get back to me. Although, the fact that you have alarms on Axes 4, 5, and 6 suggests that you lost system memory. |
