MITSUBISHI inverter series: FR-F820.
Voltage level: three phase 200V.
Power: 2.2kw.
SLD converter rated current: 16.7A.
Structure and function: Standard model.
Type: CA.
Substrate coating: have.
Compatibility with existing models.
Transducer installation size and FR-F700 (P) series of the same, so you do not need to worry about the replacement operation.
Also, but also through the use of options (FR-A8TAT), FR-F700 (P) series installed control loop terminal station.
Built in 2 PID arithmetic. In the inverter can be PID control of the motor state at the same time, used in the control of the external machine.
No external PID controller is used to control the external machine, so the system cost can be reduced.
MITSUBISHI inverter FR-A740 series.
Voltage level: 3 phase 400V.
Frequency converter capacity: 220KW.
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 FR-F820-00167-2-60.
The converter is composed of rectifier (AC), filter, inverter (DC), braking unit, driving unit, micro processing unit of the detection unit
FR-F820-00167-2-60
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 FR-F820-00167-2-60. The frequency of a transducer can be set by a digital signal from an external BCD or binary code.
BCD code 3 (maximum 999).
BCD code 4 (maximum 9999).
Binary code 12 (max FFFH).
Binary code 16 (max FFFFH). Power: 0.4kw.
Purpose: to suppress the power harmonics.
Improve the power factor, reduce the input side of the high harmonic current MITSUBISHI FR-F820-00167-2-60.
Make sure that this option is installed in the FR-A820-03800 (75K) and FR-A840-02160 (75K) and above capacity and above capacity.
At the same time the installation options in the use of 75kW and above motor MITSUBISHI IPM motor. (the IP55 series has a built-in DC reactor.)
According to the motor power used to select the DC reactor MITSUBISHI IPM motor.
(when the inverter capacity is greater than the motor capacity, is still based on the motor capacity to choose.) Power: 11kw.
Purpose: high frequency braking resistor.
The use rate of the built-in regenerative brake of the transducer can be promoted.
When using the FR-ABR type brake resistor, the short circuit piece between the terminal PR-PX is removed MITSUBISHI IPM motor. Does not remove the short circuit chip will lead to overheating of the brake resistor.
The utilization rate of the regenerative braking should be less than the allowable brake use rate in the above table.
With the operating frequency of the brake resistor to reach 3300 degrees C or higher, it is necessary to take protective measures and cooling FR-F820-00167-2-60.
MYS type resistor can be used. But please pay attention to the allowable brake use rate.
Do not remove the terminal P/+ and P1 between thhe short circuit chip, in addition to connecting the DC reactor MITSUBISHI FR-F820-00167-2-60.
The installation of thermal relay, to avoid overheating and burn the braking resistor.
