"MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 18.5KW.
The use of frequency converter motor is in order to speed, and reduce the starting current.
In order to produce a variable voltage and frequency, the device is the first power of the AC power conversion to DC (DC), the process is called rectification FR-ABR-H15K.
The direct current (DC) is transformed into alternating current (AC) and its scientific term is "inverter" (inverter) FR-ABR-H15K
General inverter is the DC power supply inverter for a certain fixed frequency and a certain voltage of the inverter.
For the inverter as the frequency adjustable, adjustable voltage inverter, we called the inverter FR-ABR-H15K. "MITSUBISHI inverter FR-A720 series .
Voltage level: 3 phase 200V.
Frequency converter capacity: 0.75KW.
Inverter output for the PWM wave, containing more harmonic.
Frequency conversion power sensor through the input voltage and current signals to exchange sampling,
Sampling value through cable, optical fiber and other transmission systems and digital input frequency conversion power analyzer,
The sampling value of the voltage and current is calculated by the digital input frequency conversion power analyzer,
It can obtain the parameters such as voltage effective value, current effective value, fundamental wave voltage, fundamental current, harmonic voltage, harmonic current, active power, fundamental wave power and harmonic power FR-ABR-H15K. Output type: bidirectional controlled silicon.
Output points: 8 points.
Load voltage: AC100-240.
Load current: 1A.
Connection mode: terminal row.
Common public end points: 4.
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.
The structured text programming language uses the computer description method to describe the various kinds of relations between the various variables in the system,
Complete the required function or operation.
Most PLC manufacturers use structured text programming language similar to BASIC language, PASCAL language or C language and other advancedd languages,
But in orderr to be convenient, the expression methods of the statement and the types of statements are simplified FR-ABR-H15K.
Structured text programming language features: the use of high-level language programming, you can complete the complex control operations,
Needd tto have a certain level of computer knowledge and programming skills,
Higher requirements for engineering designers FR-ABR-H15K. Poor visibility and operability.
