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 FR-A740-55K-CHT PDF

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-A740-55K-CHT PDF.
Therefore, if the magnetic flux decreases, the electromagnetic torque wwill decrease, which leads to the reduction of the load carrying capacity FR-A740-55K-CHT Manual. MITSUBISHI inverter series: FR-A820 FR-A740-55K-CHT PDF.
Voltage level: three phase 200V.
Power: 15kw.
SLD converter rated current: 77A.
Structure and function: Standard model.
Type: CA.
Substrate coating: have.
Parameters can be selected by 4 different rated current and different overload rating (SLD (ultra light load) rated, LD (light load) rating, ND (general load) rating, HD (weight) MITSUBISHI INSTRUCTION MANUAL.
Type load) for selection.
You can choose the most suitable frequency converter for use; and by selecting a transducer with a SLD or LD rated level,
Be able to reduce the size of the device (compared with the FR-A700 series, to reduce the volume of equipment) MITSUBISHI INSTRUCTION MANUAL.
For applications that require high torque at low speeds, the HD rating is the most suitable.
The controller is used to control and monitor the frequency converter through the network.
Standard corresponding RS-485 communication (MITSUBISHI converter protocol, Modbus-RTU protocol) data transmission speed up to 115200bps MITSUBISHI INSTTRUCTION MANUAL FR-A740-55K-CHT INSTRUCTION MANUAL. Power: 7.5kw.
Voltage: 400V.
Purpose: high frequency braking resistor.
The braking ability provided by the braking capacity is larger than that provided by the external braking resistor.
Can also be connectedd without built-in brake transistor inverter FR-A740-55K-CHT Manual.
Three types of discharge resistors are available.
Please select according to the required braking torque.
