"Power: 30kw.
Voltage: 200V.
Brake resistor, a kind of ripple resistance, is mainly used in the mechanical system of the inverter to control the speed of the motor,
Help the motor to be converted into heat energy due to the regenerative power of the motor.
Braking unit principle: the brake unit is composed of a high power transistor GTR and its driving circuit FA-TH16Y2TR20 PDF datasheet.
Its function is to link the discharge current braking resistor capacitor voltage or not in the range of the time consumed and the DC part "overpressure",
Need to add external braking components, in order to speed up the speed of the consumption of renewable energy FA-TH16Y2TR20 "Power: 1.5kw.
Purpose: to suppress the power harmonics.
Improve the power factor, reduce the input side of the high harmonic current FA-TH16Y2TR20 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 FA-TH16Y2TR20 PDF datasheet. ) The number of output channels: 4 channels.
Voltage output: DC-10~10V.
Current output: DC0~20mA, DC-4~20mA.
Programmable logic controller: FX2NC, FX3UC.
By using analog input module and output module,
Can be input and output analog (voltage, current, etc.).
Indispensable analog control in FA control,
It is easy to implement on a programmable logic controller. MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 560KW.
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.
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 mmotor FA-TH16Y2TR20 PDF catalog FA-TH16Y2TR20 PDF catalog.
Therefore, if the magnetic flux decreases, the electromagnetic torque will decrease, which leads to the reduction of the load carrying capacity.
