What to do if Hitachi Inverter shows over current detection at output stage?
- M
  Malik ChristensenAug 20, 2025
  If the Hitachi Inverter experiences over current detection at the output stage, it could be due to a rapidly changing load or a short circuit/earth contact in the motor or motor cable. To resolve this, if fast deceleration is happening, preset the Decel time longer. Also, check the wires if any motor is locked. Reduce the value if high preset torque boost is enabled, and verify if the preset DC injection brake level is high. Finally, check for any CT malfunction or noise.

What to do if Hitachi L300P Inverter detects overload at output stage with motor?
- C
  Cheryl RodriguezAug 22, 2025
  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?
- A
  Alexander EdwardsAug 25, 2025
  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?
- S
  Steven BeckAug 26, 2025
  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?
- B
  Brandon HullAug 27, 2025
  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?
- J
  Jackie MillsAug 29, 2025
  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 shows over voltage detection after BRD %ED was run out?
- J
  Jesus WellsAug 31, 2025
  If the Hitachi Inverter shows an over voltage detection after BRD %ED was run out, it might be due to a fast deceleration during a busy running cycle. Perform the adjustment referring to d103, to reduce the BRD usage ratio.

What causes incoming over voltage detection in Hitachi L300P Inverter?
- C
  charleneperrySep 2, 2025
  If the Hitachi Inverter detects an incoming over voltage, it may be due to high incoming voltage, excluding deceleration implement input ACL.

What causes instant power failure detection in Hitachi L300P Inverter?
- J
  James StanleySep 4, 2025
  If the Hitachi Inverter detects an instant power failure, it could be due to a drop in the incoming AC voltage or contact failure in MCB, Mg.

What causes over heat detection in Hitachi Inverter?
- B
  browndonaldSep 6, 2025
  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.
