Drive unit.
MITSUBISHI universal AC servo amplifier MELSERVO-J4 series.
Rated output: 37kw.
Interface: universal type.
Power supply: three phase AC200V.
Special specifications: full closed control 4 wire / support mechanical end encoder ABZ phase input / support positioning mode.
Support position control, speed control, torque control MR-J3-40A PDF.
Position control to follow the position instructions MR-J3-40A
When the control is inserted, the position control is performed.
Speed control follows the speed command to control the speed within a certain range.
Torque control to follow the torque command to control the stable torque.
Function of switching amplitude. The increase in the process of switching and stopping,
And in the operation of the use of the switching signal, switching growth MR-J3-40A PDF. Type: MR-J_B series.
Rated output: 0.6KW.
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.
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 MR-J3-40A PDF.
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 the function, then tthere is a measuring servo and power servo system;
Analog servo and power servo system; position servo and acceleration servo system MR-J3-40A datasheet.
The electric servo system can be divided into two categories: DC DC servo system and AC AC servvo system based on the electrical signals MR-J3-40A datasheet.
AC AC servo system also has two kinds of asynchronous motor servo system and synchronous motor servo system.
