ATV650 (Altivar Process ATV600 Series) Fault Code List
1. Fornitura & Input Side Faults
1. IPF / IPL Input phase loss / 3-squilibrio di fase
Causa: Missing input phase, blown fuse, severe 3-phase voltage unbalance, 3-phase detection enabled incorrectly for single-phase supply
Rimedio: Check incoming circuit breaker / fusibili; 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
Rimedio: Increase deceleration time; 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
Rimedio: Estendere il tempo di decelerazione; enable stall prevention; installare l'unità di frenatura + resistor

4. UVF DC bus undervoltage
Causa: Mains dip, momentary power loss, loose incoming connections, contactor chatter
Rimedio: Controllare l'alimentazione; extend undervoltage delay; improve wiring connections

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

2. Produzione & Motor Side Faults
1. OCF Output overcurrent
Causa: Motor locked rotor, shorted output cable, rottura dell'isolamento del motore, rapid acceleration/deceleration
Rimedio: Disconnect motor and run no-load test; reduce acceleration/deceleration ramps; test cable insulation to earth with megger

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

3. OPF2 / OPF Output phase loss (perdita di fase del motore)
Causa: Loose motor terminals, open output contactor, small motor running at light load
Rimedio: 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, rotore bloccato, motor thermal current ITH parameter set too low
Rimedio: Ridurre il carico; adjust motor thermal current ITH; wait for motor to cool before reset

5. OLC Drive hardware current limit overload
Rimedio: Ridurre il carico; check output for short circuits; lower carrier frequency

6. OTF1 / OTF2 Motor PTC thermistor overheat
Causa: Motor winding overtemperature, broken or shorted PTC probe
Rimedio: 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: Ventola di raffreddamento guasta, clogged filter, insufficient mounting clearance, temperatura ambiente elevata, heavy dust accumulation
Rimedio: Clean air filter; check cooling fan; set fan permanent ON mode; maintain vertical ventilation clearance; monitor heatsink temperature parameter THD

2. OHFd DC reactor overtemperature
Rimedio: Ridurre il carico; improve enclosure ventilation

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

2. bOF Braking resistor overload
Rimedio: Select higher resistance braking resistor; prolungare il tempo di decelerazione

5. Safety Circuit Faults (STO Safe Torque Off)
1. SAFF STO safety circuit fault
Causa: Mismatched timing between STOA and STOB (time difference >1 S), broken wiring, internal hardware fault
Rimedio: 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)
Stato: STO terminals open, drive locked; reset only after restoring STO wiring

6. Comunicazione & Analog Signal Faults
1. CnF1~CnF4 Communication link fault (ModBus TCP / RS485)
Causa: Damaged Ethernet cable, incorrect termination resistor, Conflitto di indirizzi IP, electrical noise interference
Rimedio: 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 aperto, signal below 4 mA
Rimedio: Check transmitter and signal wiring; lower wire-break threshold if required

3. AOF Analog output fault

7. Internal Hardware Faults (InF series, generally hardware damage)
1. InF8 Internal power supply fault (power board supply abnormal)
Rimedio: Full power cycle; repeated fault = replace power board

2. InFL (InF21) Real-time clock fault, keypad communication failure
Rimedio: Remove keypad, remove battery and re-power; replace keypad; if fault persists, sostituire la scheda di controllo

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

8. Process-specific Faults (Pompa / 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
Rimedio: 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)
Rimedio: Verify pump suction availability; adjust dry-run current threshold

9. Other General Faults
1. FrF Frequency feedback fault (encoder wire break)
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. Auto-reset: Enable automatic retry via parameter Atr
2. Ripristino manuale: 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
