Fault symptom: Abnormal display.
Fault analysis: The high-voltage LED indicator light of the frequency converter is on, and the LED indicator light on the main control board is also on, indicating that the frequency converter switch power supply is normal. The DC voltage on the motherboard and main control board is also normal, such as 5V, 10V, 15V, 24V. Later, when using an oscilloscope to test the main control board, it was found that one chip HC245 had input voltage and signal, but no output signal, which may be due to its damage
Reason for fault: Users may frequently use the frequency converter to plug and unplug the operation panel with power, causing damage to the chip HC245 on the main control board.
Fault handling: Replace the chip HC245. (For reference only)
