MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 132KW.
Frequency converter common frequency of a given way: the operator keyboard is given, the contact signal given, analog signal given, the pulse signal given and communication methods given, etc..
These frequencies have their advantages and disadvantages, and should be selected according to the actual needs FR-F720-S90K PDF datasheet FR-F720-S90K
Frequency converter is a power control device which uses the power of the power semiconductor device to change the power frequency to another frequency,
Can realize the asynchronous motor soft start, variable frequency speed regulation, improve the operation precision, change the power factor, over current / over voltage / overload protection and other functions FR-F720-S90K PDF datasheet. Connecting cable for handheld RH GOT and PLC.
Cable length: 10 meters.
Application: RS-422 connection and RS-232C connection. 8 point analog potentiometer function expansion board.Analog input expansion board (2 channel).
Can be installed in FX1N, PLC FX1S, providing 2 channel analog input of the board.
Because it is embedded in the PLC installation, so do not need to install space FR-F720-S90K PDF datasheet.
Can be mixed with the use of voltage input and current input. MITSUBISHI inverter FR-F720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 0.75KW.
When the inverter is running, the starting current and starting torque of the motor are how?
With the operation of the inverter, with the acceleration of the motor to improve the frequency and voltage,
The starting current is limited to 150% below the rated current (according to the different types of aircraft, 125%~200%).
Starting with power frequency power supply, the starting current is 6~7 times of the rated current, therefore, the impact on the mechanical and electrical.
The inverter drive can be smoothly sttart (start time longer) FR-F720-S90K PDF catalog.
The starting current is 1.2~1.5 times of the rated current, and the starting torque is 70%~120% rated torque;
For the inverter with the torque automatic enhancement function, the starting torque is more than 100%, which can start with full load FR-F720-S90K PDF catalog. Life is 30000 hours, and the user can simply change the background light.
Application Series: F930GOT.
