How to solve the problem of inverter overload?

When the inverter has an overload fault, it may cause certain damage to the machine, so this problem needs to be solved in time. Generally speaking, inverter overload is mainly caused by unreasonable inverter parameters, motor overload, brake failure, poor cable wiring, etc. The following will introduce the solution to inverter overload in detail from two aspects: specific reasons and solutions.

1. Specific reasons

1. Unreasonable setting of inverter parameters

During operation, the inverter needs to set its parameters differently according to different loads and working conditions, such as PID regulator, motor overload protection, brake and other parameters. If these parameters are not set correctly, the inverter will have an overload fault.

2. Motor overload

Motor overload is one of the common causes of inverter overload. If the motor load exceeds its rated load during operation, the inverter will be overloaded and fail. In this case, the problem can be solved by increasing the motor power or replacing a high-power motor.

3. Brake failure

If the machine needs to perform emergency stops frequently during operation, and the brake fails, the inverter will be overloaded and fail. To solve this problem, the brake needs to be replaced in time.

4. Poor cable wiring

Poor cable wiring is also a reason for inverter overload. If there is a problem with the wiring, the signal transmission will be poor, which will lead to motor load problems. In this case, it is necessary to recheck the wiring, re-plan the wiring layout and other measures to solve the problem.

2. Solution

1. Check/adjust parameters

If the inverter fails to be overloaded, you need to check and adjust its parameters first. Reasonable parameter settings can enable the inverter to better adapt to different workloads, thereby avoiding overload. To ensure the correctness of the parameters, you need to fully understand the specifications and performance of the inverter, and continuously optimize and adjust during use.

2. Increase motor power

If motor overload is the cause of inverter overload, you can consider increasing the motor power. At the same time, it is also necessary to evaluate the rated load and overload degree that the motor can withstand, so as to ensure that the motor can withstand the load under the normal working state of the inverter.

3. Replace the brake

If it is found that the brake failure is the cause of the inverter overload, the brake needs to be replaced in time. When replacing the brake, it is necessary to ensure its stability and reliability, and pay attention to the compatibility with the inverter and motor to ensure that the system can work properly.

4. Check the cable wiring

Checking whether the cable wiring is correct and re-planning the wiring layout can avoid poor signal transmission and motor load problems. The cable wiring layout needs to fully consider factors such as the length, material, and circuit connection method of the cable, and make reasonable adjustments according to the situation to avoid overload problems.

Summary:

The inverter overload problem is one of the common faults. When a fault occurs, it is necessary to promptly select the correct solution for the specific cause. These methods need to be targeted and reasonable to avoid unnecessary waste and losses. To ensure the normal operation of the inverter and the machine, the inverter overload problem must always be treated with the right attitude.
