ATV650 (Altivar Process ATV600 Series) Fault Code List
1. 공급 & Input Side Faults
1. IPF / IPL Input phase loss / 3-위상 불균형
원인: Missing input phase, 끊어진 퓨즈, severe 3-phase voltage unbalance, 3-phase detection enabled incorrectly for single-phase supply
치료: Check incoming circuit breaker / 퓨즈; set IPL to nO to disable phase loss detection if running on single-phase supply

2. OVF DC bus overvoltage
원인: Mains voltage too high, deceleration time too short, regenerative energy from high-inertia loads
치료: 감속시간을 늘린다; fit braking resistor; activate adaptive deceleration brA

3. ObF Overvoltage stall (trip due to excessive DC bus voltage)
원인: 빠른 감속, high load inertia, excessive regenerative energy
치료: 감속시간 연장; enable stall prevention; 브레이크 유닛을 설치하다 + 저항기

4. UVF DC bus undervoltage
원인: Mains dip, momentary power loss, loose incoming connections, contactor chatter
치료: 전원 공급 장치를 확인하세요.; extend undervoltage delay; improve wiring connections

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

2. 산출 & Motor Side Faults
1. OCF Output overcurrent
원인: Motor locked rotor, shorted output cable, motor insulation breakdown, rapid acceleration/deceleration
치료: Disconnect motor and run no-load test; reduce acceleration/deceleration ramps; test cable insulation to earth with megger

2. SCF Output short-circuit / 지락
원인: Damaged motor cable shorted to earth, motor winding earth fault, failed drive IGBT
치료: Disconnect motor and test drive output separately; measure motor winding insulation to earth

3. OPF2 / OPF Output phase loss (모터 위상 손실)
원인: Loose motor terminals, open output contactor, small motor running at light load
치료: 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
원인: Continuous overloading, 잠긴 로터, motor thermal current ITH parameter set too low
치료: 부하 감소; adjust motor thermal current ITH; wait for motor to cool before reset

5. OLC Drive hardware current limit overload
치료: 부하 감소; check output for short circuits; lower carrier frequency

6. OTF1 / OTF2 Motor PTC thermistor overheat
원인: Motor winding overtemperature, broken or shorted PTC probe
치료: 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)
원인: Failed cooling fan, clogged filter, insufficient mounting clearance, 높은 주변 온도, heavy dust accumulation
치료: 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
치료: 부하 감소; improve enclosure ventilation

4. Braking Circuit Faults
1. bUF Braking circuit fault
원인: Open braking resistor, failed braking IGBT, 느슨한 배선
치료: Check braking resistor resistance and connections; test braking unit at no load

2. bOF Braking resistor overload
치료: Select higher resistance braking resistor; 감속 시간을 연장하다

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

6. 의사소통 & Analog Signal Faults
1. CnF1~CnF4 Communication link fault (모드버스 TCP / RS485)
원인: Damaged Ethernet cable, incorrect termination resistor, IP 주소 충돌, electrical noise interference
치료: Inspect cables; use shielded communication cable; verify IP settings; reduce baud rate

2. AIF Analog input wire break (4–20 mA current signal)
원인: Broken sensor cable, 개방 회로, signal below 4 엄마
치료: 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)
치료: Full power cycle; repeated fault = replace power board

2. InFL (InF21) Real-time clock fault, keypad communication failure
치료: Remove keypad, remove battery and re-power; replace keypad; if fault persists, replace control board

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

8. Process-specific Faults (펌프 / fluid functions exclusive to ATV650)
1. iPPF Low inlet pressure protection (dry-run / low suction protection)
원인: 입구 압력이 충분하지 않음, faulty pressure transmitter, protection threshold set too high
치료: 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)
치료: 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. 자동 재설정: Enable automatic retry via parameter Atr
2. 수동 재설정: 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
