MITSUBISHI inverter FR-A740 series.
Voltage level: 3 phase 400V.
Frequency converter capacity: 75KW.
Frequency converter is the application of frequency conversion technology and micro electronics technology, by changing the motor operating power frequency mode to control the AC motor power control equipment MITSUBISHI .
The converter is composed of rectifier (AC), filter, inverter (DC), braking unit, driving unit, micro processing unit of the detection unit MR-H10TN
Inverter by the internal IGBT to adjust the output power supply voltage and frequency,
According to the actual needs of the motor to provide the required power supply voltage, and then achieve the purpose of energy saving, speed control, in addition to the,
Inverter has a lot of protection functions, such as over current, over voltage, overload protection and so on MITSUBISHI . Twisted pair / rubber insulated cable.
Single bus.
LINK MELSEC-I/O (control unit).
According to the control requirements of the system, using the appropriate design method to design MITSUBISHI PLC program MITSUBISHI .
Procedures to meet the requirements of system control as the main line,
Write one by one to achieve the control function or the sub task of the program,
Gradually improve the functions specified by the system .
MITSUBISHI PLC initialization procedure. After MITSUBISHI PLC on power, the general need to do some of the initial operation,
In order to start making necessary preparations, to avoid the wrong operation of the system.
The main contents of the initialization program are: to some data area, counter and so on,
Data needed to restore some of the data area,
Set or reset some relays,
For some initial state display, etc.. MITSUBISHI inverter FR-D740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 2.2KW.
The internal and back of the inverter structure considering the cooling effect, the relationship between the upper and lower ventilation is also important,
Therefore, in order for the type of unit, hanging on the wall to the vertical position, the installation of vertical as possible.
Transducer can be used to drive a single phase motor? Can single phaase power supply be usedd?
Basically can not be used MITSUBISHI MR-H10TN. For a single phase motor with governor switch, the auxiliary winding will be burnt when the speed is below the operating point;
For the capacitor start or capacitor operation mode, the capacitor exxplosion will be induced MITSUBISHI MR-H10TN.
The inverter power supply is usually 3, but the capacity for small, single-phase power is also useful functioning aircraft.
