The acceleration and deceleration time parameters of the frequency converter can usually be adjusted through the operation panel of the frequency converter or the corresponding software. The following takes Yaskawa frequency converters as an example to detail how to adjust the acceleration and deceleration time parameters:
1. Adjust through the operation panel
Connect the frequency converter: Ensure that the frequency converter is correctly connected to the motor and that the motor rotates in the correct direction.
Enter the parameter setting menu:
Press the "MENU" key on the inverter operation panel to enter the parameter setting menu.
Use the increase and decrease keys to select the parameter group that needs to be adjusted. Usually, the acceleration and deceleration time parameters are located in Group C.
Select the acceleration and deceleration time parameters:
Among the parameters in Group C, find the two parameters C1-01 (acceleration time 1) and C1-02 (deceleration time 1). Use the increase key and the decrease key to select these two parameters, and press the "DATA/ENTER" key to /confirm/i.
Set parameter values:
Use the increase key and decrease key to set the required acceleration and deceleration time values. These values can be adjusted according to the actual application requirements, but it is recommended not to exceed the allowable range of the frequency converter or motor.
After the Settings are completed, press the "DATA/ENTER" key again to /confirm/i.
Save the parameters and exit:
Press the "MENU" key to return to the previous level of the menu and check whether the set parameters have been saved correctly.
If necessary, you can use the "ESC" key to return to the previous state or exit the parameter setting menu.
Restart the inverter: After adjusting the parameters, it is recommended to restart the inverter to ensure that the Settings take effect.
2. Through software adjustment (taking DriveWizard Plus as an example)
Software connection: Connect the computer to the Yaskawa A1000 frequency converter via a USB cable and start the DriveWizard Plus software.
Select connection: In the software, choose "Connect -USB" to establish communication with the frequency converter.
Select parameters: In the software, select the acceleration and deceleration time parameters that need to be adjusted, namely C1-01 (acceleration time 1) and C1-02 (deceleration time 1).
Set parameter values: Enter the required acceleration and deceleration time values in the software and confirm the Settings.
Download parameters: After the Settings are completed, select "Write Parameters" in the menu bar and download the parameters to the frequency converter. If the software is directly closed, the parameters cannot be written into the frequency converter.
View modified parameters: If you need to view the modified parameters, you can select "Modified Parameters" in the parameter bar for viewing.
3. Precautions
Parameter range: When setting the acceleration and deceleration time, ensure that the set values do not exceed the allowable range of the frequency converter or motor.
Load conditions: The setting of acceleration and deceleration time should take into account the inertia of the load and the actual demand to ensure that the motor can start and stop smoothly.
Debugging and testing: After adjusting the parameters, debugging and testing should be carried out to ensure the normal operation of the system. Each parameter can be checked one by one and fine-tuned.
Professional guidance: If you are not familiar with the parameter adjustment process or encounter any problems, it is recommended to consult relevant professionals or the inverter manufacturer for professional guidance.
By following the above steps, you can successfully adjust the acceleration and deceleration time parameters of the Yaskawa inverter to meet the actual application requirements.
