How to deal with the overheating fault of the frequency converter?
When this occurs, initially assess the operational status of the cooling fan by manually checking its functionality. If the fan is operating normally, ascertain whether the ambient temperature is excessively high, if there are inadequate ventilation provisions for the inverter, or if there is a malfunction in the temperature detection circuit.

If the motor fails to operate, what steps should be taken?
Inspect the motor, wires, and inverter for any signs of damage, ensuring that the wires are securely connected. Verify if the "RUN" button on the keyboard is illuminated and check for any error codes displayed. Validate whether the frequency parameters are accurately configured, including frequency source selection, upper and lower frequency limits, and set frequency.

How to deal with no display on the screen of the inverter after powering it on?
If the power indicator light is illuminated, potential causes for the keyboard display issue may include: 1. Damage or short circuit in the power supply board; 2. Poor connectivity of the keyboard cable; 3. Damage to the main control board. If the power indicator light is not illuminated, possible reasons for this failure could be: 1. Absence of input power; 2. A broken fuse; 3. Damaged rectifier bridge.

What steps should be taken in the event of a discrepancy between the actual speed and the set speed?
In open-loop operation, the inverter outputs the specified frequency, while the motor's speed fluctuates within the range of the rated slip rate (1%-5%) during operation with a load. In situations where precise control accuracy at high speeds is required, even when there are changes in load, and the motor needs to operate close to the specified speed, a variable-frequency drive equipped with a PG feedback function (optional accessory) can be utilized a...
