MITSUBISHI inverter series: FR-F820.
Voltage level: three phase 200V.
Power: 3.7kw.
SLD converter rated current: 25A.
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 series: FR-A800.
Voltage level: three phase 400V.
Power: 2.2kw.
SLD converter rated current: 8.3A.
Structure and function: Standard model.
Type: CA.
Substrate coating: have.
Excellent drive performance.
FR-A800 series equipped with the latest high-speed processor. Has better control performance and response speed,
Products to ensure stable and accurate operation in a wide variety of applications FR-F820-00250-2-60
FR-F820-00250-2-60
Enhanced real-time sensorless vector control and vector control functions, can meet the needs of various kinds of machinery and equipment.
For paper, textile, wire, a variety of tape and other products of the extension of the machine processing, linear speed control is essential FR-F820-00250-2-60.
It can respond quickly to the change of production line speed and avoid the phenomenon of uneven winding.
This helps to achieve a stable supply of high quality products. Parameter setting can be carried out without the power supply of the inverter.Power: 7.5kw.
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 FR-F820-00250-2-60. 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 300 degrees C or higher, it is necessary to take protective measures and cooling.
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 the short circuit chip, in addition to connecting the DC reactor.
The installation of thermal relay, to avoid overheating and burn the braking resistor. Power: 15kw.
Voltage: 400V.
There are 100% braking torque output in ccontinuous regeneration, which can correspond to the continuous regeneration operation of the pipeline control FR-F820-00250-2-60.
There is no need to install the braking unit for each frequency converter, which can reduce the comprehensive space annd reduce the comprehensive cost FR-F820-00250-2-60.
Renewable energy can be used for other frequency converter, excess energy back to the grid, to achieve energy saving.
