Modbus communication and address assignment for Mitsubishi PLC

1. Consultation question: FR-A700 series Mitsubishi inverter, the suffix is ending in -CA1, what kind of inverter? Solution: The suffix -CA1 is a special model with take-up control. 2. Consultation question: FR-A ...

In the process of using the PLC control system, it is often necessary to correct some parameters, and the most common is to correct the set value of the timer. In order to facilitate the operator to correct the set value of the timer, the following methods can be used: 1. The use of man-machine ...

1. Descend the starting current of the motor When the motor is started, due to the influence of inertia and load, there will be a large starting current. This current causes fluctuations in grid voltage and energy additions to the grid. The use of frequency converters can effectively solve this problem. After conditioning inverter ...

On November 5, 2021, the 4th China International Import Expo was grandly held at the National Convention and Exhibition Center in Shanghai. At the 4th CIIE, Mitsubishi Electric's booth was located in Hall 4.1 of the Technical Equipment Zone of the Convention and Exhibition Center, with an exhibition space of 400 square meters. At Mitsubishi Electric's booth, the high-profile event was ...

The capacity (non-functional) of the Mitsubishi inverter of the drive motor can be understood from the change in energy activity determined by the operating method. 1. When operating at speed or constant speed The efficiency of the inverter is the output current, which is the ...

There is a very common kind of circuit in Mitsubishi PLC - the persistence circuit. The insistence circuit means that when the external input switch is a button, it can be pressed once through the insistence circuit to insist on the output, similar to the self-locking in the electrical diagram. We use Mitsubishi PLC as an example to write a sticking circuit. ...

How do I adjust the built-in moments in my Mitsubishi PLC? In the case of Mitsubishi PLC, sometimes technical engineers forget to adjust the PLC well, but they also need to pay attention to some key points and introduce how to adjust the built-in moments in Mitsubishi PLC. ...

GT1020 touch screen ● The palm is large, the wide screen displays, and the ultra-small size is 3.7 inches ●3-color LED backlight for added visibility ●High brightness liquid crystal, clear under light ● Resolution 160×64, standard memory 512K ●Inside ...

1. The cause of the failure (1) Unreasonable mechanical design leads to excessive radial load force; (2) The load side is stuck, or the moment of severe overload; (3) The motor and reducer are not centered when installed; 2. Fault cleaning ...

Mitsubishi PLC's Memory is a memory device in the measurement muscle system that is used to store processes and data. The overall information in the measuring machine, including the output of the original data, the measuring machine process, the central operating cut-off and the final operating cut-off are stored in the memory. It is based on the controller ...

PLC is an industrial small computer, it has a problem, the first thing to clean up is the PLC ontology problem is still a peripheral problem, if there is a problem with the PLC ontology, often the ERR light is on, maybe the red light is flashing, the normal situation is generally RUN running green light, if it is the ontology to produce this kind of problem, ...

1. Aging of drive circuit Due to the long-term use, it will inevitably lead to the aging of components, and then cause the drive waveform to be distorted, and the output voltage will be unstable, so OC alarm often appears as soon as it is running. ...

(1) Arbitrary axis AC command (G140) G140 Instruction Address = Axis Address Instruction Address = Axis Address ... ; Command Address: Arbitrary Axis AC Command (G140) After that, specify the 1-character address set by the parameter (#12071-#12078) to be used for moving commands, etc.

1 SET Directive The SET instruction is called an enthronement instruction. Its function is: to drive the coil, so that it has a self-locking function, and insists on the connection condition. In the diagram, when the moving contact X0 is closed, the SET command is executed to turn on the Y0 coil. After X0 is disconnected, the Y0 coil continues to insist on the ON condition, ...

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 ...

There is electrostatic capacitance between the input and output wiring of Mitsubishi inverters and other wires, between the ground and the motor, and there is a leakage current flow. The leakage current value is affected by factors such as electrostatic capacitance and carrier frequency, and the leakage current is high when the carrier frequency of the inverter is set high and the leakage current is operated under low noise conditions.

Mitsubishi inverter has many setting parameters, each parameter has a certain selection range, and the use of individual parameters is often improper, resulting in the inverter can not operate normally. Let's take a look at the Mitsubishi inverter parameter setting operation. ...

Mitsubishi PLC is widely used in digital control systems. At present, equipment long-distance control plays an important role in long-distance data collection, PLC long-distance fault diagnosis, and PLC long-distance programming. This article takes the long-distance control of Mitsubishi PLC as an example, and after the HiNet intelligent gateway of Huachen Zhitong ...

Q: When will I choose the D740 series inverter? A: D700 is a multi-function compact inverter, more portable, less than E700, the general function can be basically realized, simple start and stop can use D700 series. Q: How should Mitsubishi inverter D740 ...
