MITSUBISHI FR-A7ND Product information and technical parameters：
Brand: MITSUBISHI
Name: Net Device communication module
Model: FR-A7ND
Purpose: to operate, monitor, and change the parameters through the network.
Applicable frequency converter: FR-A700, FR-F700, FR-E700.
"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 FR-A7ND.
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 FR-A7ND "MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V FR-A7ND.
Frequency converter capacity: 250KW.
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 motor FR-A7ND.
Therefore, if the magnetic flux decreases, the electromagnetic torque will decrease, which leads to the reduction of the load carrying capacity. "Power: 55kw.
Voltage: 400V.
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 powwer of the motor FR-A7ND.
