How to debug parameters of constant voltage inverter

Debugging the parameters of the constant voltage inverter is an important step to ensure its normal operation and meet the operating requirements. The following is a general constant voltage inverter parameter debugging process:

1. Understand system requirements: First, understand the load properties, working characteristics and requirements of the system, including the motor rated current, rated speed, working environment, etc. This will help determine the goal and direction of parameter debugging.

2. Set basic parameters: According to the motor and application requirements, set some basic parameters, such as rated voltage, rated frequency, inverter capacity, etc. These parameters can usually be completed in the parameter setting menu of the constant voltage inverter.

3. Parameter setting: According to the motor performance and control requirements, some key parameters are set. Common parameters include:

Motor parameters: Enter the motor's rated current, rated speed, number of poles, etc.

Speed ​​loop parameters: including speed proportional coefficient, speed integral time, speed dead zone, etc.

Current loop parameters: including current proportional coefficient, current integration time, overload protection, etc.

Acceleration/deceleration time: Set the acceleration and deceleration time according to the actual working conditions and application requirements.

These parameters are usually set and adjusted in the parameter menu of the inverter. For specific values ​​and parameter configuration methods, please refer to the operating manual and technical specifications provided by the equipment manufacturer.

4. Normal operation test: After completing parameter setting, connect the constant voltage inverter to the load and gradually increase the load to reach the designed working condition. Monitor and adjust the working status of the inverter, including stability, speed control accuracy, overload protection, etc.

5. Real-time monitoring and adjustment: Once the constant voltage inverter is operating normally, it is recommended to regularly monitor and adjust its working status to ensure its performance and stability. This includes monitoring parameters such as current, speed, temperature, etc., and adjusting parameters in a timely manner as needed.

When debugging the constant voltage inverter parameters, it is recommended to refer to the operating manual and technical specifications provided by the manufacturer and proceed under the guidance of an experienced electrical engineer or control expert.

How to select the timing control of constant voltage inverter

Constant voltage inverters usually have a timing control function, which can automatically open and close according to a preset schedule. The steps to select timing control are as follows:

1. Determine your needs: First, determine the specific needs for applying timing control. For example, you want to start and stop a device during a specific time period every day, or control the operation of the device according to a weekly plan. Knowing your timing control needs is very important for subsequent settings and adjustments.

2. Check the device function: confirm whether the constant voltage inverter has the timing control function. This requires reference to the inverter's product manual, technical manual or device parameter list. Make sure the device supports timing control and has the corresponding timing control interface or function.

3. Set the timing control parameters: Enter the parameter setting menu of the constant voltage inverter and find the parameter options related to timing control. The specific setting steps may vary depending on the inverter model and manufacturer, but generally include the following aspects:

Schedule setting: Set the start and stop time of each time period according to your needs. You can set a specific time every day or a certain day/days of the week.

Action settings: Set the actions that need to be performed within a specific time period, such as start, stop, running status, etc.

Execution mode setting: Select recursive mode or single mode. Recursive mode means that the timing control will be repeated periodically according to the set schedule. Single mode means that it will only be executed once and will not be repeated.

4. Save and start timing control: After completing the above settings, save the settings and switch the inverter's operating mode to timing control mode. Depending on the requirements of the device, other operations may be required, such as authorization, password verification, etc.

5. Real-time monitoring and adjustment: Once the timing control starts working, it is recommended to monitor its execution in real time to ensure that the operation is consistent with expectations. When using the timing control function for the first time or changing the schedule, it is best to test and verify to confirm the accuracy and stability of the settings.

The timing control function of each constant voltage inverter may be slightly different. The specific setting steps should refer to the operating manual and technical specifications provided by the equipment manufacturer.
