invt drive fault codes list - if you are facing any fault in INVT drive then these fault codes list will help you to identify cause and its solution.
Below list show invt drive fault codes list:
- ETH2 - Grounding shortcut fault 2: This means an ground fault overcurrent flows due to an earth fault that occurred on the inverter's output side (load side).
- LL - Electronic underload fault: This means the inverter will report the underload pre-alarm according to the set value.
- PoFF - input voltage is too low: This means the input power supply is out of phase, and the drive voltage detection circuit is faulty.
- ItE - Current detection fault: This means the connection of the control board is not good due to hardware issue in drive control card or power card.
- tE - Autotuning fault: This means the motor capacity does not comply with the inverter capability and the rated parameter of the motor does not set correctly.
- EEP - EEPROM error: This means the function code parameter writing error. This fault comes when hardware issue in control card of drive.
- PIDE - PID feedback error: This means the PID feedback offline. A "PID feedback fault" in "INVT" drive typically refers to an error or issue related to the PID.
- bCE - Brake unit fault: This means the braking line or braking pipe is broken or brake resistor rating is too lower.
- END - Time reach of factory setting: This means the actual running time of the inverter is above the internal setting running time.
- PCE - Keypad communication error: This means the keypad is not in good connection or offline or the part of the communication circuits of the keypad or main board have fault.
- UPE - Parameter upload error: This means the keypad is not in good connection or offline and the part of the communication circuits of the keypad or main board have fault.
- DNE - Parameter download error: This means the keypad is not in good connection or offline and the part of the communication circuits of the keypad or main board have fault.
- ETH1 - Grounding shortcut fault 1: This means an ground fault overcurrent flows due to an earth fault that occurred on the inverter's output side (load side).
- OU3 - Over voltage when constant speed: This means the inverter's internal main circuit DC voltage to reach or exceed the specified value.
- OL1 - Motor overload: This means the output current exceeds the motor full load current set in parameter.
- OL2 - Inverter overload: This means the output current has exceeded due to load too heavy or acceleration too fast.
- OL3 - Electrical overload: This means the inverter will report overload pre-alarm according to the set value.
- SPI - Input phase loss: This means the input R,S,T have phase loss or imbalance. An Input Phase Loss "SP1" fault will occur when the DC bus ripple exceeds a pre-defined level.
- SPO - Output phase loss: This means the open phase is present in the motor or when you run drive without motor.
- OH1 - Heat-sink over heat: This means the heatsink temperature reaches the overheat fault level. The drive will display "oH1"
- OH2 - IGBT overheat: This means the heatsink temperature reaches the overheat fault level.
- EF - External terminal fault: This means the external fault at multi-function input terminal or faults comes from external control circuit.
- CE - Communication error: This means there is no control data was received from the connected PLC when using serial communications.
- OUt1 - IGBT Phase-U fault: This means there's an issue related to IGBT Phase-U in the power stage of the drive, specifically affecting a particular phase's voltage.
- OUt2 - IGBT Phase-V fault: This means there's an issue related to IGBT Phase-V in the power stage of the drive, specifically affecting a particular phase's voltage.
- OUt3 - IGBT Phase-W fault: This means there's an issue related to IGBT Phase-W in the power stage of the drive, specifically affecting a particular phase's voltage.
- OC1 - Over current in Acceleration: This means the over current during Acceleration. This fault appears when the motor is drawing excess current during acceleration.
- OC2 - indicates Over current in Deceleration: This means the deceleration time too short, large load inertia or inverter power rating too small.
- OC3 - Overcurrent when constant speed running: This means the abrupt fluctuations in the load or abnormal load conditions.
- OV1 - Over Voltage when Acceleration: This means the inverter's internal main circuit DC voltage to reach or exceed the specified value.
- OV2 - Over voltage when deceleration: This means the drive internal main circuit DC voltage to reach or exceed the specified value.
- OV3 - Over voltage when constant speed: This means the inverter's internal main circuit DC voltage to reach or exceed the specified value.
- OU1 - Over Voltage when Acceleration: This means the inverter's internal main circuit DC voltage to reach or exceed the specified value.
- OU2 - Over voltage when deceleration: This means the drive internal main circuit DC voltage to reach or exceed the specified value.
This list show detailed descriptions of each fault code, including potential causes and recommended solutions.
