MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 315KW.
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 FR-E720S-1 FR-E720S-1.5K5K datasheet PDF catalog FR-E720S-1.5K PDF datasheet.
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 heating of the motor FR-E720S-1.5K datasheet PDF catalog FR-E720S-1.5K PDF datasheet.
Therefore, if the magnetic flux decreases, the electromagnetic torque will decrease, which leads to the reduction of the load carrying capacity. Can be isolated from the output of the programmable controller, the a/b/c contact relay, SSR, Tr output.Power: 0.75kw.
Purpose: to suppress the power harmonics.
Improve the power factor, reduce the input side of the high harmonic current FR-E720S-1.5K datasheet PDF catalog FR-E720S-1.5K PDF datasheet.
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. (the IP55 series has a built-in DC reactor.)
According to the motor power used to select the DC reactor.
(when the inverter capacity is greater than the motor capacity, is still based on the motor capacity to choose.) Power supply: 110mA DC5V (PLC internal power supply), 90mA DC24V (external power supply).
Analog input points: 4 points.
Voltage input: DC-10~10V.
Current input: DC-20~20mA, 4~20mA.
Weight: 0.2kg.
Dimensions: 55 x 90 x 87.
Voltage input and current input of 4 channels can be carried out,
Each channel can be specified as a current input or voltage input FR-E720S-1.5K datasheet PDF catalog FR-E720S-1.5K PDF datasheet.
Built in digital filter function and peak hold function, etc.,
Achieved a high speed of 500 AD S/ch conversion FR-E720S-1.5K datasheet PDF catalog FR-E720S-1.5K PDF datasheet.
FX3U-4AD can connect FX3GA/FX3G, FX3GE, FX3U series.
When connecting to FX3UC or FX3GC, you need FX2NC-CNV-IF or FX3UC-IPS-5V.
