ATV650 (Altivar Process ATV600 Series) Fault Code List
1. Suministrar & Input Side Faults
1. IPF / IPL Input phase loss / 3-desequilibrio de fase
Causa: Falta fase de entrada, fusible quemado, severe 3-phase voltage unbalance, 3-phase detection enabled incorrectly for single-phase supply
Recurso: Check incoming circuit breaker / fusibles; set IPL to nO to disable phase loss detection if running on single-phase supply

2. OVF DC bus overvoltage
Causa: Mains voltage too high, deceleration time too short, regenerative energy from high-inertia loads
Recurso: Aumentar el tiempo de desaceleración; fit braking resistor; activate adaptive deceleration brA

3. ObF Overvoltage stall (trip due to excessive DC bus voltage)
Causa: Fast deceleration, high load inertia, excessive regenerative energy
Recurso: Ampliar el tiempo de desaceleración; enable stall prevention; instalar la unidad de frenado + resistor

4. UVF DC bus undervoltage
Causa: Mains dip, momentary power loss, loose incoming connections, contactor chatter
Recurso: Compruebe la fuente de alimentación; extend undervoltage delay; improve wiring connections

5. PHF Supply phase sequence error
Recurso: Swap any two incoming phases L1/L2/L3

2. Producción & Motor Side Faults
1. OCF Output overcurrent
Causa: Motor locked rotor, shorted output cable, rotura del aislamiento del motor, rapid acceleration/deceleration
Recurso: Disconnect motor and run no-load test; reduce acceleration/deceleration ramps; test cable insulation to earth with megger

2. SCF Output short-circuit / falla a tierra
Causa: Damaged motor cable shorted to earth, motor winding earth fault, failed drive IGBT
Recurso: Disconnect motor and test drive output separately; measure motor winding insulation to earth

3. OPF2 / OPF Output phase loss (pérdida de fase del motor)
Causa: Loose motor terminals, open output contactor, small motor running at light load
Recurso: Tighten motor wiring; disable OPL phase loss detection if an output contactor is used; disable phase loss protection for small motors

4. OLF Motor thermal overload
Causa: Continuous overloading, rotor bloqueado, motor thermal current ITH parameter set too low
Recurso: Reducir la carga; adjust motor thermal current ITH; wait for motor to cool before reset

5. OLC Drive hardware current limit overload
Recurso: Reducir la carga; check output for short circuits; frecuencia portadora más baja

6. OTF1 / OTF2 Motor PTC thermistor overheat
Causa: Motor winding overtemperature, broken or shorted PTC probe
Recurso: Check motor temperature; measure PTC resistance; disable this protection if no temperature probe is fitted

3. Drive Overheating Faults
1. OHF Drive heatsink overtemperature (common fault)
Causa: Failed cooling fan, clogged filter, insufficient mounting clearance, temperatura ambiente alta, heavy dust accumulation
Recurso: Filtro de aire limpio; check cooling fan; set fan permanent ON mode; maintain vertical ventilation clearance; monitor heatsink temperature parameter THD

2. OHFd DC reactor overtemperature
Recurso: Reducir la carga; improve enclosure ventilation

4. Braking Circuit Faults
1. bUF Braking circuit fault
Causa: Open braking resistor, failed braking IGBT, cableado suelto
Recurso: Check braking resistor resistance and connections; test braking unit at no load

2. bOF Braking resistor overload
Recurso: Select higher resistance braking resistor; ampliar el tiempo de desaceleración

5. Safety Circuit Faults (Desconexión de par segura STO)
1. SAFF STO safety circuit fault
Causa: Mismatched timing between STOA and STOB (time difference >1 s), broken wiring, falla interna del hardware
Recurso: Check both STO wiring paths; ensure STOA and STOB switch simultaneously; both paths must be shorted together for bypass

2. SdF Safety function active (normal stop, not a hardware fault)
Estado: STO terminals open, drive locked; reset only after restoring STO wiring

6. Comunicación & Analog Signal Faults
1. CnF1~CnF4 Communication link fault (Modbus TCP / RS485)
Causa: Cable Ethernet dañado, incorrect termination resistor, Conflicto de dirección IP, electrical noise interference
Recurso: Inspect cables; use shielded communication cable; verify IP settings; reduce baud rate

2. AIF Analog input wire break (4–20 mA current signal)
Causa: Broken sensor cable, circuito abierto, signal below 4 mamá
Recurso: Check transmitter and signal wiring; lower wire-break threshold if required

3. AOF Analog output fault

7. Fallos internos de hardware (InF series, generally hardware damage)
1. InF8 Internal power supply fault (power board supply abnormal)
Recurso: Full power cycle; repeated fault = replace power board

2. InFL (InF21) Real-time clock fault, keypad communication failure
Recurso: Remove keypad, remove battery and re-power; replace keypad; if fault persists, reemplazar el tablero de control

3. InF1~InF7, InF9~InF30 Other internal hardware errors
Recurso: Ciclo de energía; fault cannot be cleared → control board / power board damaged, requires repair or replacement

8. Process-specific Faults (Bomba / fluid functions exclusive to ATV650)
1. iPPF Low inlet pressure protection (dry-run / low suction protection)
Causa: Insufficient inlet pressure, faulty pressure transmitter, protection threshold set too high
Recurso: Check pipeline suction pressure; calibrate pressure transducer; reduce low-pressure threshold

2. HPF High pressure protection, LPF Low pressure protection, FLF Flow fault

3. DryF Dry-run protection (pump running without fluid)
Recurso: Verify pump suction availability; adjust dry-run current threshold

9. Other General Faults

2. USF Motor autotune failed on power-up
3. CLF Cooling circuit fault (water-cooled versions only)
4. tJF Motor stall protection

10. Fault Reset Methods
1. Reinicio automático: Enable automatic retry via parameter Atr
2. Reinicio manual: Assign DI terminal function rSF for remote reset; reset via keypad
3. Internal hardware faults (InF codes): Require full power cycle; some faults need board replacement
