Drive unit.
MITSUBISHI universal AC servo amplifier MELSERVO-J4 series.
Rated output: 30kw.
Interface: SSCNET III /H.
Power supply: three phase AC400V.
Special specifications: full closed control 4 wire / support mechanical end encoder ABZ phase input / support positioning mode.
Support position control, speed control, torque control.
Position control to follow the position instructions.
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.
Drive: MR-H_ACN series CC-LINK features.
Rated output: 0.1KW.
The test system is composed of two parts, namely, the servo driver, the motor system and the host computer.
The host computer sends the speed command signal to the servo driver,
Servo drives start to run in accordance with the instructions MITSUBISHI MR-J4-DU30KB4-RJ.
In the course of operation, the running data of the servo system is collected by the host computer and the data acquisition circuit,
And carries on the preservation, the analysis and the display to the data
MR-J4-DU30KB4-RJ Because the motor is not loaded in this test system,
So compared with the previous two kinds of testing systems, the system has a relatively small volume,
And the measurement and control circuit of the system is relatively simple,
But it also makes the system can not simulate the actual operation of the servo drive MITSUBISHI MR-J4-DU30KB4-RJ.
Usually, such testing system is only used to test the rotational speed and angular displacement of the tested system under no-load condition,
And can not carry on the comprehensive and accurate test to the servo drive. Type: MR-J_B series.
Rated output: 0.6KW.
Interface: standard MITSUBISHI MR-J4-DU30KB4-RJ.
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.
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, theen there is a measuring servo and power servo system;
Analog servo and power servo system; position servo and acceleration servo system MR-J4-DU30KB4-RJ.
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-J4-DU30KB4-RJ.
AC AC servo system also has two kinds of asynchronous motor servo system and synchronous motor servo system.
