Các lỗi thường gặp ở các bộ Servo Fanuc và hướng khắc phục.
– Sửa chữa Servo Drive Fanuc DC, AC đời thấp cho các hệ điều khiển Fanuc, 3, 6, 10, 11 thường bị các lỗi như:
+ Khắc phục servo Fanuc lỗi HV : Over-voltage alarm ( This alarm occurs if the DC voltage of the main circuit power supply is abnormally high)
+ Khắc phục servo Fanuc lỗi HC : over-current alarm ( This alarm occurs if an abnormally high current flows in the axis motor)
+ Khắc phục servo Fanuc lỗi LV : Low control power voltage alarm ( This alarm occurs if the control power voltage is abnormally low)
+ Khắc phục servo Fanuc lỗi DC : Low DC link voltage alarm ( his alarm occurs if the DC voltage of the main circuit power supply is abnormally low or the circuit breaker trips)
+ Khắc phục servo Fanuc lỗi OH : Over-regenerative discharge alarm ( This alarm occurs if The average regenerative discharge energy is too high)
Sửa servo Fanuc báo lỗi số 1: The battery voltage of the absolute pulse coder is low. (warning)
Sửa servo Fanuc báo lỗi số 1 2: The battery voltage of the absolute pulse coder is low
Sửa servo Fanuc báo lỗi số 1 3: The motor has overheated (OHAL).
Sửa servo Fanuc báo lỗi số 1 5, S: A communication error for the serial pulse coder was detected.
Sửa servo Fanuc báo lỗi số 1 9: Reference position setting cannot be executed normally
Sửa servo Fanuc báo lỗi số 1 11: When the absolute pulse coder is used, the motor has not yet rotated through more than one turn after the first power–up.
Sửa servo Fanuc báo lỗi c: An overcurrent alarm or IPM alarm
Sửa servo Fanuc báo lỗi C: Faulty cooling circuit
Sửa servo Fanuc báo lỗi E: An error was detected in the RAM write/read test at power–up.
Sửa servo Fanuc báo lỗi J: The regenerative discharge unit has overheated
Sửa servo Fanuc báo lỗi P: DC link low voltage alarm
Sửa servo Fanuc báo lỗi U: A parameter that requires power–down has been specified.
Sửa servo Fanuc báo lỗi u: A first to third reference position return cannot be executed because the reference position has not yet been established.
Sửa servo Fanuc báo lỗi Y: DC link overvoltage alarm
