MITSUBISHI FR-F840-00170-2-60 datasheet PDF catalog FR-F840-00170-2-60 PDF datasheet

MITSUBISHI inverter FR-F720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 0.75KW.
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%) FR-F840-00170-2-60 datasheet PDF catalog FR-F840-00170-2-60 PDF datasheet FR-F840-00170-2-60
Starting with power frequency power supply, the starting current is 6~7 times of the rated current, therefore, the impact on the mechanical and electrical.
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-F840-00170-2-60 datasheet PDF catalog FR-F840-00170-2-60 PDF datasheet. "Power: 30kw.
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 power of the motor FR-F840-00170-2-60 datasheet PDF catalog FR-F840-00170-2-60 PDF datasheet.
Braking unit principle: the brake unit is composed of a high power transistor GTR and its driving circuit.
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. "MITSUBISHI inverter series: FR-F820.
Voltage level: three phase 200V.
Power: 18.5kw.
SLD converter rated current: 93A.
Structure and function: Standard model.
Type: CA.
Substrate coating: have.
PID target value can be set directly from the operator panel. Flexible change settings.
In the 1 inverter, through the PID control of parallel connection pump (up to 4 units) can adjust the amount of water and so on.
1 pumps driven by parallel connection of the pump machine, in addition to the pump for poower frequency drive FR-F840-00170-2-60 datasheet PDF catalog FR-F840-00170-2-60 PDF datasheet.
The number of power frequency driven pump, according to the automatic adjustment of water.
The liquid crystal panel options (FR-LU08) can be converted too a more intuitive display unit% units FR-F840-00170-2-60 datasheet PDF catalog FR-F840-00170-2-60 PDF datasheet.
Through the use of wind, temperature and other familiar units can be simple to maintain and adjust the display.
