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 HF-SP352BK
Speed control method of fan and pump equipment traditional 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 process of closure HF-SP352BK.
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. Type: MR-J_B series.
Rated output: 2.0KW.
Interface: standard.
Servo system according to the system structure can be divided into open loop servo system, closed loop servo system, semi closed loop system, compound control system HF-SP352BK.
The closed loop automatic control system with feedback is composed of a position detecting part, a deviation amplifying part, an executing part and a controlled object.
Servo system must have good controllability, high stability and high adaptability.
Note that the control of the signal is good after the disappearance of the signal, can immediately stop the turn;
High stability is the torque with the increase of speed and uniform decline; adaptability is fast, sensitive, and ring state quality is good.
According to the types of servo drives are classified, there are three kinds of electric, hydraulic or electric hydraulic.
If the servo system is divided according to tthe function, then there is a measuring servo and power servo system;
Analog servo and power servo system; position servo and acceleration servo system HF-SP352BK.
The electric servo system can be divided into two categories: DC DC servo system and AC AC servvo system based on the electrical signals HF-SP352BK.
AC AC servo system also has two kinds of asynchronous motor servo system and synchronous motor servo system.
