1. Additional torque The torque that occurs on the motor shaft under additional voltage, extra load is called the extra torque of the motor. 2. Starting torque The torque generated by the motor at the moment when a voltage is applied to the motor in the aborted condition is called the starting torque. The starting torque characterizes the electrical...

1. Disadvantages of UVT The common undervoltage detection point is the voltage on the DC bus side, and a low voltage value is sampled after dividing the voltage by the large resistance resistor, and the output voltage is normal signal, overvoltage signal or undervoltage signal after comparing with the standard voltage value. About Mitsubishi A500 series inverter voltage signal ...

In the PLC control system, the content that needs to be displayed mainly includes timer value, counter value and data register value, and the data display method can be summarized into two fundamental types: one is based on the PLC data communication interface, such as RS-232, RS-485/422, and the display device also has such an interface.

The capacity (non-functional) of the Mitsubishi inverter for the drive motor can be understood from the change in energy flow determined by the operation method. 1. When accelerating or operating at constant speed The efficiency of the inverter is the output current, that is, how much current the inverter can provide to the motor. Frequency converters ...

First, the control accuracy is different The step angle of the two-phase hybrid stepper motor is generally 1.8° and 0.9°, and the step angle of the five-phase hybrid stepper motor is generally 0.72° and 0.36°. There are also some high-performance stepper motors with smaller step angles after subdivision. Communicate the control of servo motor ...

(1) Random Access Memory (RAM) The user can read out the content of the RAM with the programming device, and can also write the user program to the RAM, so the RAM is also called read/write memory. It is volatile memory, and when its power is interrupted, the stored information is lost. The use of the computer's memory module ...

When evaluating which process is suitable for which approach in the production environment, consider the problem you want to solve and consider all the costs that the robot can save: reduce waste, improve efficiency, improve productivity, improve safety, or reduce labor costs. These costs ...

01. Base system problem In Mitsubishi PLC, there are binary, octal, decimal, 10, 2-10 (BCD), etc., we need to master the conversion of 2-8 base. 2-8, remember the binary number from the back, divide every 3 into a group, and each group is converted into octal respectively, such as 1 ...

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 ...

FX Series PLC: FX3G PLC has a built-in large-capacity program memory, 32K steps, and the basic instruction processing speed can reach 0.21μs in specification mode. In the meantime, the FX series 5U is suitable for any industry, and is used by small and medium-sized enterprises. For example, this year's very popular mask machine is suitable for FX5U, and he can ...

(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 ...

There is a capacitance between the wires of the cable, and a qualified cable can limit this capacitance to a certain size. It is a qualified cable, when the cable length exceeds a certain length, the capacitance value between the lines will also exceed the required value, when the cable is used for PLC input, the capacitance between the lines will be ...

First, Mitsubishi uses FX5U series PLC with serial port and built-in modbus communication protocol, so that we can easily communicate with third-party equipment. If it is a communication between Mitsubishi PLC and the inverter, the focus is on designing the parameters. The inverter is heavy, set the address, baud rate, check, etc., ...

1. What is suspension? The so-called suspension refers to the fact that in the process of sequentially performing the program scanning, when there is a request to respond immediately, the scanning work performed at that time is immediately suspended, and the service work specified in the request is performed first. When the service job is complete, go back to ...

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 ...

1. The ERR problem is an under-voltage problem, which is usually caused by the problem of voltage detection loop resistance or wiring, rather than the actual input voltage showing undervoltage. Most of the OC problems of the A200 series are caused by the damage of the drive circuit, and its drive circuit ...

1) LD (take instruction) A command to connect a normally open contact with the left bus, and every logic line that starts with a normally open contact is used with this instruction; 2) LDI (Reverse Instruction) A normally closed contact is connected to the left bus to the instruction, each ...

Mitsubishi Electric's fresh air system realizes indoor ventilation, but of course, we can't just be limited to simply replacing the outdoor air into the room, a good fresh air should filter the harmful substances in the air, so that the air entering the room is not only fresh, but also clean and harmless. ...

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...
