If the Hitachi Inverter experiences a power off or is waiting for AC incoming voltage recovery, it could be due to a drop in the incoming AC voltage. Check the DC bus voltage. Also, check for contact failure in MCB, Mg.
What to do if Hitachi L300P Inverter detects overload at output stage with motor?
If your Hitachi Inverter detects an overload at the output stage with the motor, it's likely due to a load that is too heavy. To address this, perform the adjustment referring to d104 to reduce the electronic thermal level.
What causes over voltage detection (DC bus voltage) in Hitachi L300P?
If the Hitachi Inverter shows an over voltage detection (DC bus voltage), this could be due to fast deceleration or earth contact (ground fault) in the motor or motor cable or back energy from the load. To solve this, perform the adjustment referring to d102, so that the DC bus voltage does not exceed the trip level. Also, check for any back energy from the load.
What causes EEPROM contradiction error in Hitachi L300P?
If the Hitachi Inverter displays an EEPROM contradiction error, it may be due to significant noise near the inverter or the ambient temperature being too high.
What causes under voltage (DC bus voltage) in Hitachi L300P?
If the Hitachi Inverter detects an under voltage (DC bus voltage), it could be due to a drop in the incoming AC voltage or insufficient power capacity or any thyristor failure. To solve this, perform the adjustment referring to d102, so that the DC bus voltage does not exceed the trip level.
What causes ground fault at power on at output stage in Hitachi Inverter?
If the Hitachi Inverter is experiencing a ground fault at power on at the output stage, it could be due to earth contact (ground fault) in the motor or the motor cable, or an IGBT failure.
What to do if Hitachi Inverter displays option card error?
If a Hitachi Inverter displays an option card error, make sure the connection of the board and if the usage is proper.
What to do if Hitachi L300P Inverter displays encoder wire cut error?
If the Hitachi Inverter shows an encoder wire cut, check the wiring for breaks or loose connections of the encoder signal. Replace the encoder if it has failed or is not a line driver output. If using an encoder without a Z phase signal, set SWENC-2 to “OFF” on the card.
What causes IGBT over current detection in Hitachi L300P?
If the Hitachi Inverter detects an IGBT over current (equivalent as power module), it could be due to a short circuit or earth contact (ground fault) in the motor or motor cable, an IGBT failure, or a loose connection on the main circuit such as the power board.
What causes over heat detection in Hitachi Inverter?
If the Hitachi Inverter detects overheating, it could be caused by a cooling fan failure, a disturbance of the cooling such as dusty fin, vertical installation, or a high ambient temperature.
