Mitsubishi inverter commissioning procedure before use
Published:2023-08-03 14:40:24
First, Mitsubishi inverter no-load power test.
1. Ground the ground terminal of the Mitsubishi frequency converter.
2 Connect the power input terminal of the Mitsubishi inverter to the power supply through the leakage maintenance switch.
3 Check whether the Mitsubishi inverter display window factory display is normal, if not correct, should be reset, otherwise require return.
4 Understand the operation keys of the inverter. The general frequency converter has 6 keys such as RUN, STOP, PROG, DATAPENTER, add (UP, ▲), reduce (DOWN, "), etc. The definition of different frequency converter operation keys is basically the same.
Two, Mitsubishi inverter with motor no-load operation
1. Set the power and pole number 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 universal frequency converter has multiple VPf curves for users to choose, and users should select the appropriate VPf curve according to the nature of the load when using.
3. Set the Mitsubishi inverter to its own keyboard operation mode, press the running key and stop key, and investigate whether the motor can start and stop normally.
4. Understand the maintenance code of Mitsubishi inverter when the operation fails, investigate the factory value of thermal maintenance relay, investigate the set value of overload maintenance, and modify it when necessary. Mitsubishi inverter users can set the electronic thermal relay function of Mitsubishi inverter according to the Mitsubishi inverter instruction manual.
Three, Mitsubishi inverter with load test run
1. Manually operate the operation stop key of the Mitsubishi inverter panel, investigate the motor operation stop process and the display window of the inverter, and see if there are abnormal phenomena.
2. If the Mitsubishi inverter shows overcurrent maintenance action in the process of starting the P stop motor, it should be reset to speed up the P deceleration time. The acceleration degree of the motor in acceleration and deceleration depends on the acceleration torque, and the frequency change rate of the Mitsubishi inverter in the starting and braking process is set by the user.
