The αi-series manufacturer's manual is used to check the relationship between 9051, 433, SPM 51 and PSM 4. Original alarm photographs are retained, with an explanation of why undervoltage must be investigated alongside power conditions and shutdown order.
Read article →Organize the original M80 S01 power-supply inrush-circuit alarm evidence, distinguish 006B from 006C and identify the model, operating-stage and repair records needed before inspection.
Read article →This preserves the original A06B-6164-H344 case involving a burnt port, 9137/D7 and SP19B replacement. The βiSVSP manual definition is added, while making clear that the outcome is not a universal component-replacement remedy for all 9137 alarms.
Read article →Retain the original MDS-D-V2-160160 no-display/Y03 record and photographs, with checks of connection, supply and axis correspondence. Live cable removal is explicitly excluded as a troubleshooting step.
Read article →A FANUC 16 display showed ghosting. Comparing IO boards and tracing display signals revealed an open connection at a CPU pin; the display returned to normal after repair. Board traces and photos are retained, with pin details limited to the board examined at the time.
Read article →A Tornos deco sigma 20 with FANUC 31i-MODEL A would not start and had no display. The original record located a short circuit in the mainboard power section. This revision separates observations from suspected supply instability and explains why historical fuse trials are not selection advice.
Read article →An A06B-6093-H112 had no indicator lights and damaged chips. After chip and fuse replacement it powered up normally, but a misconnected cable remained an unconfirmed suspicion. The comparison measurement and original photos are retained; interface data cannot be transferred between models.
Read article →A TSUGAMI B020-V developed intermittent alarm 9083 during main/subspindle synchronization. Comparisons of the drive, cable and sensors showed the alarm moving with the sensor. This revision adds interpretation and scope limits while retaining the recorded tests and photos.
