Dear Sirs
AL16 appears in AC Spindle Servo Unit A06B 6055 H322 #H540
As per Fanuc Manual for AL 16, we need to replace NVRAM
As far as we know IC22 (MBM2212-20) is NVRAM and it is mounted on a IC base - kindly confirm if this is the NVRAM which should be replaced or u suspect some problem in the PCB with respect to current sensing and data bus
Can this IC be just replaced with another MBM2212-20
Warm Regards,
