Fanuc i Series CNC Hardware

6 fault codes documented

ABTQSV

Servo axis abnormal load detected signal

This signal indicates that a servo axis in the Fanuc i Series CNC has encountered an abnormal load condition. This typically suggests the motor is drawing excessive current, potentially leading to motor overload, drive tripping, or mechanical damage.

ABTSP1

First spindle abnormal load detected signal

This signal indicates that the first spindle of the Fanuc i Series CNC has detected an abnormal load condition. This implies the spindle motor is operating beyond its normal current limits, which can cause overheating, drive trips, or damage to the motor or mechanical components.

ABTSP2

Second spindle abnormal load detected signal

This signal indicates that the second spindle of the Fanuc i Series CNC has detected an abnormal load condition. This implies the spindle motor is operating beyond its normal current limits, which can cause overheating, drive trips, or damage to the motor or mechanical components.

ABTSP3

Third spindle abnormal load detection signal

This signal indicates that the third spindle of the Fanuc i Series CNC has detected an abnormal load condition. This implies the spindle motor is operating beyond its normal current limits, which can cause overheating, drive trips, or damage to the motor or mechanical components.

BAL

Battery alarm signal

This signal indicates a low battery condition for the Fanuc i Series CNC, typically affecting the SRAM or pulse coder backup. Loss of battery power can result in the loss of critical parameters, programs, and absolute position data.

BGIALM

Power Mate read/write alarm signal

This signal indicates an issue with data reading or writing operations within the Fanuc Power Mate system integrated with the Fanuc i Series CNC. Such issues can lead to data corruption, incorrect operation, or failure to store critical data.
