MITSUBISHI inverter FR-D740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 1.5KW.
The internal and back of the inverter structure considering the cooling effect, the relationship between the upper and lower ventilation is also important,
Therefore, in order for the type of unit, hanging on the wall to the vertical position, the installation of vertical as possible FX1S/FX1N Series PDF FX1S/FX1N Series
Transducer can be used to drive a single phase motor? Can single phase power supply be used?
Basically can not be used. For a single phase motor with governor switch, the auxiliary winding will be burnt when the speed is below the operating point;
For the capacitor start or capacitor operation mode, the capacitor explosion will be induced FX1S/FX1N Series PDF.
The inverter power supply is usually 3, but the capacity for small, single-phase power is also useful functioning aircraft. Function extension board for USB communication FX1S/FX1N Series PDF.
DC5V power consumption: 0mA. "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 MITSUBISHI Lloyd's Register.
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 cappacitor 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 Lloyd's Register FX1S/FX1N Series LR. "Special module for RS-232C communication.
This serial communication module, you can communicate with the computer, printer, code reader and other equipment with RS-232C communication function.
The data can be transmitted through the buffer storage area of the module, and the data transfer between the PLC host and the module is realized MITSUBISHI Lloyd's Register.
When you connect to FX3UC, you need FX2NC-CNV-IF or FX3UC-1PS-5V. MITSUBISHI inverter FR-D720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 2.2KW.
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 orientted,
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 conttrol method, to obtain the DC motor control,
The control of asynchronous motor is realized through the corresponding inverse coordinate transformation FX1S/FX1N Series LR FX1S/FX1N Series Lloyd's Register.
