Servo motors are generally operated by three circuits. To put it bluntly, the three circuits are three closed-loop control negative feedback PID control systems. The first innermost PID loop is the current loop, which is implemented completely inside the servo controller. Exercise...

1. Torque control: Torque control is based on external simulation imitation type or direct address assignment to set the output torque of the motor shaft. For example, 10V matches 5Nm. When the external simulation simulation is set to 5V, the output of the motor shaft is 2.5Nm. Assuming that the load on the motor shaft is less than 2.5Nm, then ...

The use of Mitsubishi AC servo system is mainly composed of three series: MR-ES, MR-J2S, MR-J3. In general, the cause of the fault can be preliminarily determined based on the code displayed on the servo drive, and then troubleshooting: 1、AL. E6 - Indicates ...

Q: When will I choose the A840 series inverter? A: A800 series inverters are generally used in heavy-duty occupations, such as lifting occupations, mixer occupations will use A800 series. At the same time, it is a vector inverter, so customers need to do closed-loop speed control, torque control may ...

Method 1 1. Hit the PLC from RUN to STOP Mitsubishi's PLC has a special method of setting landing keywords, and it is necessary to ensure that the PLC is in a state of shutdown in order to successfully write the landing keywords. In the run running condition, the performance of the write will appear "Unable to ...

1. The servo mainly relies on the pulse to position, basically it can be understood in this way, the Mitsubishi CNC system repair servo motor receives 1 pulse, it will rotate the angle corresponding to 1 pulse, and then complete the displacement, because, the servo motor itself has the function of announcing the pulse, so the servo motor ...

1. Characteristics of the output reactor: 1. It is suitable for reactive power compensation and harmonic control 2. The primary effect of the output reactor is to compensate for the influence of long-line distributed capacitance, and output harmonic current according to the press; 3. Effectively protect the Mitsubishi inverter and improve the power factor, which can block the ...

1. DC servo The structure is simple and easy to operate. However, considering the actual operation, the DC servo motor has introduced mechanical equipment for reversing installation, which increases the cost, has many problems, and is inconvenient to maintain, and often interferes with the production and manufacturing due to the sparks of carbon brushes, and electromagnetic interference will occur. Combine...

First, the control accuracy is different The step angle of the two-phase hybrid Mitsubishi servo motor is generally 1.8 ° and 0.9 °, and the step angle of the five-phase hybrid Mitsubishi servo motor is generally 0.72 ° and 0.36 °. Mitsubishi servo motors are also smaller in some functions according to the segmentation. Such as Sanyo ...

First of all, what are the advantages of servo motors compared with other motors (such as stepper motors): 1. Accuracy: Closed-loop control of azimuth, speed and torque is realized; Overcome the problem of stepper motor out-of-step; 2. Speed: high speed ...

The current value of the motor is used as the basis for the selection of the inverter, and the rated power of the motor is only for reference. Compared with the general squirrel cage motor, the winding motor simply has the problem of overcurrent tripping, and the slightly larger capacity than the usual ...

The intuitive method refers to the search and analysis of faults based on the external manifestations of Mitsubishi inverter defects without any instruments. The visual method includes an unpowered view and a power-on survey. In the overhaul, the first thing to do is to check without power, that is, to use the human sensory organs (eyes, ears, hands, nose) to check the relevant plug-in.
