The servo control system is a kind of operating system which can automatically control the mechanical movement of the test device according to the predetermined requirements MR-J2S-70A Manual MR-J2S-70A Instruction Manual MR-J2S-70A
In many cases, refers to the servo system is to control the amount of (the system output) is a feedback control system of mechanical displacement or displacement velocity and acceleration,
Its function is to make the output of the mechanical displacement (or rotation angle) to accurately track the input displacement (or rotation angle) MR-J2S-70A Manual MR-J2S-70A Instruction Manual.
The structural composition of the servo system and other forms of feedback control systems are not distinguished in

principle. Drive: MR-H_ACN series built-in positioning function.
 

Rated output: 0.4KW.
In servo drive speed closed loop,
Rotor speed measurement accuracy is very important to improve the dynamic and static characteristics of the speed control loop MR-J2S-70A Manual MR-J2S-70A Instruction Manual.
In order to seek the balance between measurement precision and system cost, incremental photoelectric encoder is generally used as the speed measuring sensor,
The corresponding method is M/T velocity measurement.
Although the M/T measurement method has a certain measurement accuracy and a wide range of measurement,
 

But this method has its inherent defects,

Mainly includes: the measurement period must be detected at least one complete encoder pulse, limiting the minimum detectablee speed MR-J2S-70A Manual MR-J2S-70A Instruction Manual.
2 control system for speed control of the timer switch is difficult to maintain synchronization,
Can not guarantee the accuracy of measurement in the situation where the speed change is largger MR-J2S-70A Manual MR-J2S-70A Instruction Manual.
Therefore, it is difficult to improve the speed tracking and control performance of servo drive by using the traditional speed loop design method.
