MITSUBISHI FR-F720-55K TECHNICAL MANUAL

MITSUBISHI inverter FR-A740 series.
Voltage level: 3 phase 400V.
Frequency converter capacity: 37KW.
Frequency converter is the application of frequency conversion technology and micro electronics technology, by changing the motor operating power frequency mode to control the AC motor power control equipment FR-F720-55K .
The converter is composed of rectifier (AC), filter, inverter (DC), braking unit, driving unit, micro processing unit of the detection unit FR-F720-55K
Inverter by the internal IGBT to adjust the output power supply voltage and frequency,
According to the actual needs of the motor to provide the required power supply voltage, and then achieve the purpose of energy saving, speed control, in addition to the,
Inverter has a lot of protection functions, such as over current, over voltage, overload protection and so on FR-F720-55K . MITSUBISHI inverter series: FR-A820.
Voltage level: three phase 200V.
Power: 11kw.
SLD converter rated current: 63A.
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) FR-F720-55K .
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).
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 inverter FR-F720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 11KW.
When the inverter is running, the starting current and starting torque of the motor are how?
With the operation of the inverter, with the acceleration of the motor to improve the frequency and voltage,
The starting current is limited to 150% below the rated current (according to the different types of aircraft, 125%~200%).
Starting with power frequency power supply, the starting current is 6~7 times of the rated currrent, therefore, the impact on the mechanical and electrical FR-F720-55K TECHNICAL MANUAL.
The inverter drive can be smoothly start (start time longer).
The starting current is 1.2~1.5 times of the rated current, and the starting torque is 70%~120%% rated torque;
For the inverter with the torque automatic enhancement function, the starting torque is more than 100%, which can start with full load FR-F720-55K TECHNICAL MANUAL.
