See my post in this thread for some useful parameters.

Also, power machine down. Hold the following buttons P and CAN while powering maching back up. Hold them until machine is completely powered on. Move the axis to middle of travel then perform zero return. The P/Can tells the machine to ignore soft limits and allows it to home on limit switches.

You most likely have battery back up position encoders, if they are disconnected then you lose the recorded position and you get 3x0 alarm ZRN is Zero Return.
If you have the maintenance manual it shows in there how to record.
If you need the manual in PDF send me a PM with a email address.

Hi,

Yes, even if it was sold under Stama brand, I finally managed to kill this alarm by changing the parameter to 22 (not so sure) from 011 to 111, it was enough

Still if you have the full manual I would really appreciate if you can share it.
