"MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 15KW.
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 FX3U-232ADP .
The direct current (DC) is transformed into alternating current (AC) and its scientific term is "inverter" (inverter)
FX3U-232ADP
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 FX3U-232ADP .
Voltage level: three phase 200V.
Frequency converter capacity: 110KW.
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) FX3U-232ADP .
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. Input points: 24 points.
Output points: 16 points.
Power supply voltage: AC160-240V.
Output type: relay output.
Built in CPU, power supply, input and output. While maintaining the convenience of FX1N while improving performance.
Special adaptor and function expansion board can be installed and used FX3 series.
High speed operation.
Basic instructions: 0.21 s/ instruction.
Application instruction: 0.5 s/ instruction.
Large capacity memory.
Built in program memory 32000 steps.
EEPROM memory cartridge with program transfer function. MITSUBISHI inverter FR-E720 series.
Voltage level: 3 phase 200V.
Frequency converter capacity: 0.75KW.
In order to ensure the reliability of production, all production machinery in the design of power with drive, there is a certain amount of surplus.
When the motor can not run under full load, in addition to meet the requirements of power driven,
The surplus torque increases the active power consumption, resulting in the waste of electric energy.
Speed control method of fan and pump equipment tradditional by regulating the entrance or exit of the baffle, valve opening to regulate air flow and water flow
, the input power is large, and a large amount of energy consumption in the baffle, the valve in the processs of closure FX3U-232ADP INSTALLATION MANUAL FX3U-232ADP INSTALLATION MANUAL.
When using variable frequency control, if the flow rate is reduced, the speed of the pump or fan can be reduced to meet the requirements.
