The installation process of Yaskawa frequency converters requires meticulous care to ensure a successful installation and stable operation of the frequency converters. The following are the main steps of Yaskawa inverter installation:
1. Prepare
Confirm the model and parameters: Confirm the model, capacity, and power supply voltage and current of the inverter to ensure that they match the actual application scenario.
Preparing tools and materials: Prepare required installation tools, cables, ground cables, and other materials based on installation requirements.
2. Install the frequency converter
Select the installation location: Choose a smooth, stable and well-ventilated location to install the inverter, ensuring sufficient space for heat dissipation and maintenance.
Fixed frequency converter: Install the frequency converter in the selected position, and use the appropriate fixing method (such as screws) to firmly fix it.
3. Electrical connection
Connect the power supply: Connect the power input of the inverter to the power line to ensure that the power line meets the requirements of the inverter and is connected without error. Check whether the phase sequence of the power supply is correct and whether the voltage is consistent with the rated voltage of the inverter.
Connect the input power: according to the model and specifications of the inverter, connect the corresponding input power line, and take appropriate protection measures.
Connect the output power supply: Connect the output end of the inverter to the power supply line of the load device. Select an appropriate output cable based on the current and voltage requirements of the load. Ensure that cables are properly connected.
Grounding: According to the requirements of the frequency converter, the metal shell of the frequency converter is reliably connected to the ground wire to ensure electrical safety.
4. Debugging and testing
Wiring debugging: carry out the wiring debugging of the inverter to ensure that all the wiring is correct and carry out the necessary electrical safety insulation test.
Parameter setting: Use the parameter setting tool to set the parameters of the inverter and configure the appropriate control parameters and protection parameters to meet the needs of practical applications.
Startup test: Connect the control input interface of the inverter to the controller, and perform startup test. Check the working status of the inverter, speed control and various protection functions are normal.
5. Security measures
Disconnect the power supply: Before wiring, commissioning, or maintenance, disconnect the power supply to the inverter and ensure that there is no residual voltage.
Non-professionals do not move: Non-electrical construction professionals do not perform maintenance, inspection or part replacement to prevent the risk of electric shock.
Compliance with safety procedures: During the entire installation and commissioning process, strict compliance with safety operating procedures to ensure the safety of personnel and equipment.
6. Other precautions
Electrostatic protection: When operating the inverter, follow the steps specified in Electrostatic Prevention Measures (ESD) to prevent static electricity from damaging the internal circuit of the inverter.
Cable selection: When selecting cables, ensure that the specifications and quality of the cables meet the requirements of the frequency converter to avoid faults caused by cable problems.
Regular inspection: After the installation is completed, the inverter should be checked and maintained regularly to ensure that it is in good working condition.
