The power consumption of secondary low torque load devices such as fans and pumps is directly proportional to the third power of the rotational speed.
Adjusting the air volume through the speed control of the frequency converter can reduce power consumption.
Fully utilize the performance of the motor.
Always adjust the excitation current to a good state, which can greatly improve the efficiency of the motor.
When the load torque is small, it can further improve the energy-saving effect.
For example, when using a universal motor, the optimal excitation control method at 4% motor load torque improves the motor efficiency by about 30% compared to V/F control.
Power: 11kw.
Purpose: For power harmonics.
Improve power factor and reduce high-order harmonic current at the input end.
Ensure that the option is installed in capacities FR-A820-03800 (75K) and above, as well as Mitsubishi FR-F840-00023-2-60 in capacities FR-A840-02160 (75K) and above.
Install this option when using motors of 75kW and above. (IP55 series has built-in DC reactor FR-F840-00023-2-60)
Choose a DC reactor based on the motor power used.
When the frequency converter capacity is greater than the motor capacity, the selection is still based on the motor capacity. Mitsubishi frequency converter series: FR-A800.
Voltage level: three-phase 400V.
Power: 11.0kw.
Rated current of SLD frequency converter: 31.0A.
Structural functionality: Standard model Mitsubishi FR-F840-00023-2-60.
Type: CA.
Substrate coating: Yes.
Excellent driving performance.
The FR-A800 series is equipped with a new high-speed processor. With better control performance and response speed,
The product can ensure stable and efficient operation in a variety of applications.
Strengthen real-time sensorless vector control and vector control functions to meet the needs of various machine equipment.
For the machining of extended products such as paper, textiles, wires, and various tapes, linear speed control is essential for Mitsubishi FR-F840-00023-2-60.
It can respond quickly to changes in production line speed and avoid uneven winding.
This helps to achieve a stable supply of high-quality products. Excellent rate IPM motor.
Output power: 22kw.
Rated speed: 1500r/min.
Voltage level: 400V.
The IPM motor MM-EFS series cannot use a power frequency power supply to drive the Mitsubishi IP55 frequency converter with a built-in DC reactor.
The total length of wiring for IPM motors shall not exceed 100m.
One frequency converter cannot connect multiple IPM motors simultaneously. Mitsubishi frequency converter FR-F720 series.
Voltage level: three-phase 200V.
Frequency converter capacity: 75KW.
When the loop is open, even if the frequency converter outputs a given frequency, when the motor is running under load,
The speed of the motor varies within the range of rated slip (1%~5%), and the Mitsubishi IP55 frequency converter has a built-in DC reactor.
For situations where high speed regulation accuracy is required and even load changes require operation at speeds close to the given speed,
A frequency converter with PG feedback function (optional) can be used.
If the given acceleration time is too short, the output frequency of the converter changes far more than the speed (electrical Angular frequency),
The frequency converter will trip and stop operation due to overcurrent, which is called stall. The Mitsubishi IP55 frequency converter has a built-in DC reactor. Mitsubishi frequency converter series: FR-A820.
Voltage level: three-phase 200V.
Power: 0.4kw.
Rated current of SLD frequency converter: 4.6A.
Structural functionality: Standard model.
Type: CA.
Substrate coating: Yes.
Four different rated currents and overload levels can be selected through parameters (SLD (light load) rating, LD (light load) rating, ND (general load) rating, HD (heavy load
Rated load is available for selection.
You can choose the suitable frequency converter according to the purpose; And by selecting a frequency converter with SLD or LD rated level,
Capable of reducing device size (compared to the FR-A700 series, reducing device volume) FR-F840-00023-2-60.
For applications that require high torque at low speeds, the HD rating level is suitable for Mitsubishi FR-F840-00023-2-60.
The controller is used to control and monitor the frequency converter through the network.
The data transmission speed of RS-485 communication (Mitsubishi frequency converter protocol, Modbus RTU protocol) corresponding to the standard is as high as 115200bps.
