Hello everyone, I have a Nakamura Tome CNC lathe, with a Fanuc Series 15 controller, that has recently started giving the SV003 abnormal current in servo error on both axes.
The problem happened halfway through cutting a part, and strangely on both axis at the same time with both a20b-1003-0081 servo amplifiers having the HC led on.
I have already changed the a16b-2200-0080 dual axes positoning module, but the two SV003 alarms still occur straight after power up. I have also checked the +5, +15,-15 voltages on the PSU and they are all within in +/- 5%.
Could this really be both servo amplifiers or motors failing at the same time?
I appreciate any help with this, Thanks.
