MITSUBISHI inverter FR-A740 series.
Voltage level: 3 phase 400V.
Frequency converter capacity: 0.4KW.
FR-A700 converter products are suitable for all kinds of high load requirements of the equipment.
Such as lifting, lift, printing and dyeing, printing and dyeing, material coiling and other general occasions.
High level driving performance.
A wide variety of mechanical equipment can be operated at high precision in the super low speed region without the need of the encoder.
And in the speed control mode can use the torque limit function.
Frequency converter can achieve position control and fast response, high precision speed control (zero speed control, servo lock, etc.) and torque control.
"MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 2.2KW.
The use of frequency converter motor is in order to speed, and reduce the starting current.
In order to produce a variable voltage and frequency, the device is the first power of the AC power conversion to DC (DC), the process is called rectification MITSUBISHI FR-A740-0.4K-CHT.
The direct current (DC) is transformed into alternating current (AC) and its scientific term is "inverter" (inverter)
FR-A740-0.4K-CHT
General inverter is the DC power supply inverter for a certain fixed frequency and a certain voltage of the inverter.
For the inverter as the frequency adjustable, adjustable voltage inverter, we called the inverter. "MITSUBISHI inverter FR-F720 series MITSUBISHI FR-A740-0.4K-CHT.
Voltage level: three phase 200V.
Frequency converter capacity: 55KW.
When the ring is opened, the frequency converter is provided with a load of the motor when the motor is operated with a load at a given frequency,
The range of the motor speed in the rated slip ratio (1%~5%) changes.
For the requirements of relatively high precision, even if the load changes are also required to operate at a given speed of the occasion,
Inverter with PG feedback function can be used (selection) MITSUBISHI FR-A740-0.4K-CHT.
If the given acceleration time is too short, the output frequency of the inverter is far more than the change of the speed (electric angular frequency),
Converter will be due to flow over the current trip, the operation stopped, which is called stall MITSUBISHI IPM motor MITSUBISHI IPM motor. The output signal can open collector output inverter host standard.
Can be from the voltage output terminal (AM0), the current output terminal (AM1) output analog signal (output frequency, output current, etc.).
Can be connected to the 20mA DC or 10V DC meter. "MITSUBISHI inverter FR-F720 series MITSUBISHI IPM motor.
Voltage level: three phase 200V.
Frequency converter capacity: 3.7KW.
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 cuurrent, therefore, the impact on the mechanical and electrical FR-A740-0.4K-CHT.
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 MITSUBISHI FR-A740-0.4K-CHT.
