MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 280KW.
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-F740-55K-CHT
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-F740-55K-CHT.
Therefore, if the magnetic flux decreases, the electromagnetic torque will decrease, which leads to the reduction of the load carrying capacity. Protective film for 4.5 inch screen.
Scrub (frame: white), 5.
Applicable model: GT1030. MELSECNET/10, MELSECNET/H coaxial.
Input voltage: AC100-240V.
How to choose MITSUBISHI PLC.
MITSUBISHI PLC options include the choice of MITSUBISHI PLC models, capacity, I/O module, power, etc FR-F740-55K-CHT. .
MITSUBISHI PLC distribution I/O points and design MITSUBISHI PLC peripheral hardware circuit
Draw the I/O point of the PLC and the input / output device connection diagram or the corresponding table,
This part also can be carried out in second steps.
Design PLC peripheral hardware circuit.
Draw the electrical wiring diagram of the other parts of the system,
Including the main circuit and the control circuit does not enter the PLC, etc..
The electrical schematic diagram of the system composed of I/O PLC connection diagram and PLC peripheral electrical circuit diagram.
So far the system''s hardware electrical circuit has been determined. Motor series: low inertia, medium capacity.
Rated output power: 30.0kw.
Rated speed: 1000rpm.
With the brake: without.
Voltage: 400V level.
Shaft end: strraight shaft FR-F740-55K-CHT.
The rottor of the servo motor is a permanent magnet, which is controlled by the U/V/W,
The rotor rotates under the action of the magnetic field, and the encoder feedback signal of the motor is given to the driver,
According to the feedback value and the ttargget value, the driver adjusts the rotation angle of the rotor FR-F740-55K-CHT.
Accuracy of the servo motor depends on the accuracy of the encoder (number of lines).
