Mitsubishi inverter overload fault judgment method
1. Check whether the three-phase electricity of the motor is balanced
(1) If the three-phase voltage of the motor is unbalanced, then check whether the three-phase voltage at the output end of the Mitsubishi inverter is balanced.
(2) If the three-phase voltage of the Mitsubishi inverter is also unbalanced, the problem is inside the Mitsubishi inverter, and it should be investigated.

The weight conversion method of the Mitsubishi weigh module
Component conversion is a process in which an analog signal (load converter output voltage) input from outside the programmable controller is converted into a digital output value and a total component output value, and then stored in buffer memory. After the conversion process, the conversion completion (XE) will change to ON, and the transformation completion mark (Un\G1 ...

The difference between the measurement of ordinary motors and inverter motors - Mitsubishi
1. The actual output waveform of the inverter is PWM wave, which contains carrier signals in addition to the fundamental wave. The carrier signal frequency is much higher than that of the fundamental wave, and it is a square wave signal, which contains a lot of higher harmonics, and the test system requires a higher sampling frequency and bandwidth.

How to adjust the jitter phenomenon of Mitsubishi servo motor
(1) Prerequisites
Mitsubishi servo motors are able to improve the inertia of the motor by adjusting the gain, so as to adapt to the load, but the Mitsubishi servo motor is able to improve endlessly. Under normal circumstances, it is considered that it can withstand within 10-15 times of the additional inertia of the motor, and Mitsubishi reducer is required to be added in addition. We know ...
