Failure supply Faulty supply voltage Supply voltage fault inside the drive Possible cause Check the device power reset and restart. If the fault still occurs, contact your SIEI representative
Undervoltage The undervoltage DC bus drops below 65% of the rated value. The most common reason is the power failure of the device. The internal fault of the inverter may also cause an undervoltage fault. If the voltage is interrupted temporarily, reset it and restart it.
Check the device input If the device is normal and there is an internal fault, contact your SIEI dealer
Over voltage The dc link voltage inside the inverter exceeds 35% of rated value
The deceleration time is too short The device is affected by high overvoltage peaks. Adjust the deceleration time
IGBT
Desaturat IGBT fault The frequency converter has detected an erroneous operation in the IGBT bridge or its gate drive. Interference Fault device Reset and restart. If the fault still occurs, contact your SIEI representative
Inst
Over current The inverter has detected excessive motor current (>4*In)
Suddenly overloaded motor cable Short circuit motor is not suitable Check load Check cable Check motor specification
Ground fault Earth fault current detection found that the sum of the motor phase currents is not zero Motor or cable insulation failure Encoder faults may also cause earth faults Check the motor cable
Curr fbk loss Current feedback fault regulation board and current transformer connection error;
Check the connection cable of the XTA terminal
Module OT module overtemperature IGBT module too high temperature Fan failure Power element IGBT fault Overload current cycle too fast
Heatsink OT radiator overheat GBT module temperature too high Fan failure Power element IGBT fault Overload current cycle too fast
Motor OT motor overheating The motor temperature model detects the overheating of the motor. Motor overload reduces the motor load. Check the temperature module if the motor is not overheated.
Heatsink S OT Radiator sensor overheating Ambient temperature too high Fan failure Radiator too dirty Check cooling air flow Check if the heat sink is dirty Check the ambient temperature
Regulation S OT Regulator Sensor Overheat Conditioner Temperature too high Ambient temperature too high Check ambient temperature Check cooling air flow
Intake air S OT Ambient temperature sensor Overheating Cooling air temperature too high Fan failure Cooling block blocked Check fan Check inverter cooling outlet
Cont fbk fail contactor feedback fault frequency contactor main contactor fault check frequency converter contactor
Commcardfault communication fault Inverter communication fault reset Restart, if it appears again contact your SIEI dealer
Appl card fault Failed to read the option board Failed to check the installation If the installation is correct, contact your SIEI dealer
Drive overload Drive overload Drive overload
Motor overload Motor overload Motor overload Reduce motor load
BU overload overload of brake unit
Data lost Data loss
