MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 355KW.
The main circuit of the inverter can be divided into two categories in general: voltage type is the voltage source of the DC converter for AC inverter,
The filtering of the DC circuit is the capacitance; the current mode is the DC conversion of the current source to the AC inverter,
The DC loop filter is the inductor FX3G-40MT/ES-A PDF FX3G-40MT/ES-A
Why is the frequency of the inverter voltage proportional to the change?
The electromagnetic torque of any motor is the result of the interaction between the current and the magnetic flux, the current is not allowed to exceed the rated value, otherwise it will cause the heaating of the motor FX3G-40MT/ES-A PDF FX3G-40MT/ES-A Manual.
Therefore, if the magnetic flux decreases, the electromagnetic torque will decrease, which leads to the reduction of the load carrying capacity. Power: 75kw.
Purpose: to suppress the power harmonics FX3G-40MT/ES-A PDF.
Connected to the inverter input, can be used to improve the power factor, reduce the input side of the high harmonic current.
According to the motor power used to select AC reactor.
(when the inverter capacity is greater than the motor capacity, is still based on the motor capacity to choose MITSUBISHI PROGRAMMING MANUAL. ) MITSUBISHI inverter FR-E740 series.
Voltage level: 3 phase 400V.
Frequency converter capacity: 0.4KW.
Allow short-time overload (200% 3S).
The machine itself does not need to purchase another operating panel.
Provide USB interface to connect with the computer, you can use the FRConfigurator software to set the parameters of the inverter or monitor MITSUBISHI PROGRAMMING MANUAL.
Inverter surface with PU interface, FR-E500 operating panel can be directly connected to the E700 series. The installation dimensions are in full agreement wwith FR-E500 FX3G-40MT/ES-A PROGRAMMING MANUAL.
Allow side by side installation, saving installation space
Simple maintenance: equipped with comb type wiring board, wiring more convenient, the replacement of the same series inverter, no stitches, as long as thee original inverter control terminal MITSUBISHI PROGRAMMING MANUAL FX3G-40MT/ES-A Manual. Extension board for connection with special adapters
(FX1S and FX1N host general).
