MITSUBISHI inverter FR-D720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 0.75KW.
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 FX1S-30MR-001 PDF FX1S-30MR-001 PDF FX1S-30MR-001 Input / output type: transistor output (source).
Output points: 16 points.
DC5V internal consumption current: 100mA.
DC24V internal consumption current: 125mA.
In order to extend the input output of the device.
Also has a built-in power supply products.
The maximum number of points for the input and output is 256 FX1S-30MR-001 PDF.

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 oof the pump machine, in addition to the pump for power frequency drive FX1S-30MR-001 datasheet.
The number of power frequency driven pump, according to the automatic adjustment of water.
The liquid crystal panel options (FR-LU08) can be converted too a more intuitive display unit% units FX1S-30MR-001 datasheet.
Through the use of wind, temperature and other familiar units can be simple to maintain and adjust the display.
