OVF30 inverter is an inverter equipped in the 300VF control system of early OTIS elevators. Due to its long service life (at least 10 years), the probability of damage to the ABA26800XU1 (or XU2) board in the inverter is relatively high. I have repaired it. There are also a lot of frequency converters. Now I will share with you the faults that are easy to damage and not easy to find. If there are any shortcomings, please point out.
Fault 1: The power on is normal, the main board of the inverter displays X04A, and the maintenance is started. The UDX light on this board keeps on and off, and the UDX relay keeps pulling and closing, and the BRK light is not on.
Fault point: This fault is generally caused by a problem with the IGBT drive signal circuit to the drive board, generally caused by the increase in the resistance value of R118-R124=499 ohm resistors, and the problem can be solved by replacing the bad resistors.
