What are the Common Faults of KONE Elevator Inverter?

Because KONE elevator inverters are frequently driven and typically operate with high current, they have a relatively high failure rate as elevator control equipment. Common faults encountered during KONE elevator inverter maintenance include:

1. Severe shaking during elevator operation.
2. Short circuit fault in the inverter, causing the elevator power supply to trip.
3. The elevator suddenly crashes; if there is a power outage, the elevator can resume normal operation, but will malfunction again after a period of time.
4. The elevator cannot operate normally under maintenance or normal conditions.

It is essential to note that when repairing a KONE elevator inverter, the indicator light on the KONE elevator panel does not necessarily indicate that the inverter is functioning correctly. Even if the indicator light illuminates repeatedly, the underlying cause is still often a fault in the elevator inverter.

When a KONE elevator is operating normally, and a fault occurs, maintenance personnel from the KONE elevator parts supplier can read the current KONE inverter maintenance code and past error codes to analyze the cause of the elevator malfunction.

Common fault codes for the Kone elevator controller repair are as follows:

0021: Circuit fault. This fault code appears when there is a malfunction in the KONE elevator's protection switch or circuit connection, or when the maintenance switch is in the maintenance state and not activated. When the elevator is operating normally, and a fault occurs, the Kone lift spare parts LOP circuit board digital display shows fault code 0021, indicating a circuit-related fault. Repair personnel need to check the circuit to find the component causing the fault.

0022 and 0023: When fault code 0022 appears, it indicates a fault in the elevator hall door electric lock switch or its wiring. Checking the elevator hall door electric lock switch or its wiring can identify the cause of the fault. When fault code 0023 appears, checking the car door electric lock switch or its wiring indicates a fault in the car door electric lock switch or its wiring. The correlation between these two codes can help identify the cause of the failure.

0026: When fault code 0026 appears in the elevator, it indicates a fault in the drive system. The drive system consists of a V3F16L frequency converter, tachometer, traction motor, and braking resistor. If any of these components malfunctions or performs poorly, fault code 0026 may occur. The V3F16L frequency converter is more prone to failure. A fault in the V3F indicator light often accompanies a fault in the V3F16L converter.

0048: When an elevator displays fault 0048, it indicates a problem with the elevator door's light panel. This fault is usually accompanied by the door failing to close. Additionally, fault 0048 is often caused by excessive dust on the door curtain surface. Simply cleaning the dust or readjusting the position of the door light curtain will resolve fault 0048.]
