Dear forum, I am in need of help regarding an APC alarm due to battery failiure over the summer vacation and I think the machine dealer is trying to rip me off.
We had replaced the backup batteries on our machine this spring, so they were nowhere near old. Over previous summer vacations we've had a voltage alarm, but never actually lost any parameters.
(Note i have tried searching the forum, but none of the previous threads have yielded a solution.)
The machine is a millturn DOOSAN PUMA 2600LSY with fanuc i-series control
We have the following alarms:
PS0302 SETTING THE REFERENCE POSITION WITHOUT DOG IS NOT PERFORMED (after trying to zero the axes)
DS0300 (Y) APC ALARM: NEED REF. RETURN
DS0300 (Z) APC ALARM: NEED REF. RETURN
DS0300 (B) APC ALARM: NEED REF. RETURN
The service guy at the dealer in my country say they have to send a technician for a full day to fix this issue. The problem is we are far away from them and they will bill a huge amount just on travel expenses. (our last visit from them landed in the 10 000 dollar range.)
When I ask if it is possible to do this remotely he just say it is not possible. I am afraid they are just trying to exploit the situation. Thoughts?
They state that the encoders need to be calibrated for all of the X, Y, Z, and sub-spindle (B) axes, and that X and Y is difficult because the Y-axis uses the X-axis as slave.
We do have a disk with all the original machine parameters.
Any help would be greatly appreciated.
Thanks,
Daniel
