The use of Yaskawa inverter involves several steps, including connection, parameter setting, commissioning, and daily operation. Here is a detailed guide:
1. Connect the frequency converter
Connect the motor: First, connect the inverter to the motor correctly. Make sure the motor wiring is correct, and check whether the motor steering meets the requirements.
Power supply: Connect the power supply of the inverter to a suitable power supply system. Note that the voltage, current and other parameters must meet the specifications of the inverter.
2. Set parameters
Enter the parameter setting mode: Enter the parameter setting mode of the inverter by pressing the button on the operation panel (such as the MENU key).
Set the motor parameters: In the parameter setting menu, select the "motor parameters" option, and input the rated power, voltage, current and other parameters of the motor. These parameters are essential for the normal operation of the inverter.
Set the operating mode: Select an appropriate operating mode as required, for example, Automatic Speed Adjustment or Manual speed adjustment. The automatic speed control mode allows the motor to automatically adjust the speed according to the load, while the manual speed control mode requires the user to manually set the speed.
Set PID parameters (if applicable) : If automatic speed control mode is selected, you also need to set PID parameters, including proportional coefficient, integral time, and differential time. These parameters will affect the speed regulation accuracy and stationarity of the motor.
Set other parameters: According to the actual demand, you can also set other parameters, such as acceleration and deceleration time, torque limit, overcurrent limit, etc.
3.Debug
Check the rotation direction of the motor: In the debugging process, first check the rotation direction of the motor is correct. If it is not correct, you need to adjust the wiring or parameter Settings of the motor.
Adjust the running speed: Adjust the running speed of the motor as needed to ensure that the motor can reach the predetermined speed smoothly and accurately during operation.
Test protection function: Test various protection functions of the inverter, such as over-current protection, over-voltage protection, etc., to ensure that the inverter can stop the motor and protect the equipment in time when an abnormal situation occurs.
4. Daily operation
Start and STOP: In daily operation, the start and stop of the motor are controlled by the RUN key and Stop key on the operation panel.
Monitor running status: Monitor the running status of the motor through the display and indicator on the operation panel, including output frequency, output current, output voltage and other parameters.
Adjustment of operating parameters: When necessary, you can adjust the operating parameters of the motor through the buttons on the operation panel, such as changing the speed, adjusting the torque, etc.
5. Precautions
Safe operation: When operating the inverter, be sure to follow the safe operation procedures to ensure personal and equipment safety.
Regular inspection: Regularly check whether the wiring of the inverter, cooling fan, cooling system and other components are working normally, and timely find and solve problems.
Avoid overload: Avoid running the inverter in overload state for a long time, so as not to damage the equipment or affect the service life.
Professional maintenance: If the inverter fails or needs maintenance, be sure to contact professional maintenance personnel for processing.
