The surge voltage of the motor can be suppressed when the 400V motor is driven by a frequency converter.
Motor suitable for 5.5 to 37kW. MITSUBISHI inverter FR-D720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 0.4KW.
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 oriented,
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 control method, to obtain the DC motor control,
The control of asynchronous motor is realized through the corresponding inverse coordinate transformation FX1N-14MT-D datasheet PDF catalog FX1N-14MT-D PDF datasheet FX1N-14MT-D datasheet PDF catalog FX1N-14MT-D PDF datasheet FX1N-14MT-D MITSUBISHI inverter series: FR-F820.

PID target value can be set directly from the operator panel. Flexible change settings.
In the 1 inverter, through the PID control of parallel connection pump (up to 4 units) can adjust the amount of water and so on.
1 pumps driven by parallel connection of the pump machine, in addition to the pump for power frequency drive.
The number of power frequency driven pump, according to the automatic adjustment of water.
The liquid crystal panel options (FR-LU08) can be converted to a more intuitive display unit% units.
Through the use of wind, temperature and other familiar units can be simple to maintain and adjust the display. RS-232 communication. Special communication adapter.MITSUBISHI inverter FR-F720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 45KW.
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 giiven speed of the occasion,
Inverter with PG feedback function can be used (selection) FX1N-14MT-D datasheet PDF catalog FX1N-14MT-D PDF datasheet.
If the given acceleration time is too short, the output frequency of the inverter is far more than thhe change of the speed (electric angular frequency),
Converter will be due to flow over the current trip, the operation stopped, which is called stall FX1N-14MT-D datasheet PDF catalog FX1N-14MT-D PDF datasheet.
