1. No-load energizing test of Mitsubishi inverter.
1. Ground the ground terminal of the Mitsubishi inverter.
2 Connect the power input terminal of the Mitsubishi inverter to the power supply through the leakage maintenance switch.
3 Check whether the factory display window of the Mitsubishi inverter is normal, if it is incorrect, it should be reset, otherwise it will be required to be returned.
4 Understand the operation keys of the inverter. The general inverter has 6 keys such as RUN, STOP, PROG, DATAPENTER, UP, ▲, and DOWN, and the boundaries of the operation keys of different inverters are basically the same.
2. Mitsubishi inverter with motor runs without load
1. Set the power and number of poles of the servo motor, and comprehensively consider the operating current of the inverter.
2. Set the maximum output frequency, fundamental frequency, and torque characteristics of Mitsubishi inverter. The general inverter is equipped with a number of VPf curves for users to choose, and users should select the appropriate VPf curves according to the nature of the load when using.
3. Set the Mitsubishi inverter to the built-in keyboard operation mode, press the run key and stop button, and check whether the motor can start and stop normally.
4. Understand the maintenance code when the operation failure of the Mitsubishi inverter, investigate the factory value of the thermal maintenance relay, investigate the setting value of overload maintenance, and modify it if necessary. The user of the Mitsubishi inverter can set the electronic thermal relay function of the Mitsubishi inverter according to the instruction manual of the Mitsubishi inverter.
3. Mitsubishi inverter with load test operation
1. Manually operate the operation stop button of the Mitsubishi inverter panel, investigate the operation abort process of the motor and the display window of the inverter to see if there is any abnormal phenomenon.
2. If the Mitsubishi inverter shows an overcurrent maintenance action during the process of starting the P abort motor, the acceleration P deceleration time should be reset. The acceleration of the motor during acceleration and deceleration depends on the acceleration torque, and the frequency change rate of the Mitsubishi inverter during the start-up and braking process is set by the user.
