MITSUBISHI inverter FR-D720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 5.5KW.
Vector control variable frequency speed control is the practice of the asynchronous motor in the three-phase coordinate system of the stator current Ia, Ib, Ic, through the three-phase to two-phase transformation,
The alternating current of Ia1Ib1 is equivalent to a two phase stationary coordinate system, and then is rotated by the rotor field oriented,
Equivalent to the DC current Im1, It1 (Im1 equivalent to DC motor excitation current in synchronous rotating coordinate system;
It1 equal to the armature current proportional to the torque, and then imitate the DC motor control method, to obtain the DC motor control,
The control of asynchronous motor is realized through the corresponding inverse coordinate transformation FX1N-485-BD Manual FX1N-485-BD User's Manual FX1N-485-BD Manual FX1N-485-BD User's Manual FX1N-485-BD Total input and output points: 16 points.
Output points: 16 points.
Output type: silicon controlled output.
FX Series in the compact body built in superior performance, and strive to operate simple.
In addition, rich options can meet the various needs of customers FX1N-485-BD Manual FX1N-485-BD User's Manual.
In the virtual factory will be rich in the function of a part of the introduction.
It is easy to control the analog quantity of the application.
Can be extended to all models in the FX series analog devices.
Function extension board, special adapter without programming can be used for communication.
FX2N extension module.
The expansion module is an input and output expansion device of the power supply from the basic unit or the expansion unit,
Can choose the relay or crystal output models, to 8 points for the unit to connect.
Can be extended to FX3GA/FX3G, FX3GE, FX3GC, as well as FX3U, FX3UC series,
When connecting to FX3UC or FX3GC, you need FX2NC-CNV-IF or FX3UC-1PS-5V.
The number of connection points depends on the basic unit and the expansion unit. MITSUBISHI inverter FR-F720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 2.2KW.
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 current, therefore, the impact on the mechanical and electrical FX1N-485-BD Manual FX1N-485-BD User's 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 FX1N-485-BD Manual FX1N-485-BD User's Manual.
