MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 450KW.
The main circuit of the inverter can be divided into two categories in general: voltage type is the voltage source of the DC converter for AC inverter,
The filtering of the DC circuit is the capacitance; the current mode is the DC conversion of the current source to the AC inverter,
The DC loop filter is the inductor FR-L740-18.5K-CHT
Why is the frequency of the inverter voltage proportional to the change?
The electromagnetic torque of any motor is the result of the interaction between the current and the magnetic flux, the current is not allowed to exceed the rated value, otherwise it will cause the heating of the motor FR-L740-18.5K-CHT.
Therefore, if the magnetic flux decreases, the electromagnetic torque will decrease, which leads to the reduction of the load carrying capacity. Input and output points: 30 points.
Power supply: AC100-240V.
Input points: 16 points.
Output points: 14 points.
Output form: transistor output (drain).
Power consumption: 21W.
Weight: 0 FR-L740-18.5K-CHT. 45KG.
Outline dimension: 100x90x75mm.
A new application model .
FX3SA is a basic model on the basis of the basic performance of FX1S above the expansion of the expansion of the new model.
FX3SA is applicable to all kinds of fields of small scale equipment which need to simulate the quantity and function of MODBUS and Ethernet.
Basic models suitable for small scale control.
Compact but powerful,
At the same time, the analog quantity and communication function, etc.. The A1SD61 high speed counting module can receive up to 50KHz of pulse signals,
The signal can be counted when the input pulse is rising and the falling time is greater than 500.
This component has a 32 bit signed binary count range,
Counter can be preset, can also use the external signal or the control program will stop counting.
Structured text language is a programming language that describes a program with a structured description of the text.
It is a programming language similar to a high level language. In large and medium
Structured text is often used to describe the relationship between the various variables in the control system based on the PLC system.
Mainly used for other programming languages more difficult to achieve the user program.
Sequential function flow chart language is designed to satisfy the sequential logic control.
The process of sequential process action is divided into steps and transformation conditions,
According to the transfer condition, the control system is distributed in the function flow sequence,
Step by step according to the sequence of actions.
Each step represents a control function, represented by the box.
In the box, the ladder logic is used to complete the task of the corresponding control function.
This programming language makes the program structure clear and easy to read and maintain,
Greatly reduce the programming workload, shorten the programming and debugging time.
Used in the system of the size of the school, procedures for more complex occasions.
Sequence function flow chart programming language features: to function as the main line, in aaccordance with thee functional flow of the order of distribution, clear, easy to understand the user program,
Avoid the defect of ladder diagram or other languages,
At the same time, the use of ladder language to avoid the use of ladder programming,
Due to the compllicaated mechanical interlock, the structure of the user program is complex and difficult to understand,
User program scan time is also greatly reduced FR-L740-18 FR-L740-18.5K-CHT.5K-CHT.
