MELSERVO-J4 grand debut.
Servo market for the star of tomorrow. World class servo products.
The new generation of MELSERVO should be what kind of? The answer to this question is already floating
Out of the water. MELSERVO-J4, it represents the whole digital, the original high performance based on an evolutionary MR-J4-20B-RJ010 datasheet PDF catalog MR-J4-20B-RJ010 PDF datasheet.
Is also fully meet the requirements of human beings and the environment MELSERVO latest masterpiece.
For example, the safety and environmental requirements for the safety of human use and the safety specifications and "to Use Easy" design.
To meet the needs of the environmental protection era of energy-saving performance.
Beyond the performance of the evolution of MELSERVO-J4, shocking debut! "Drive: MR-H_ACN series built-in positioning function.
Rated output: 2.0KW.
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.
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 detectable speed.
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-J4-20B-RJ010 datasheet PDF catalog MR-J4-20B-RJ010 PDF datasheet MR-J4-20B-RJ010 datasheet PDF catalog MR-J4-20B-RJ010 PDF datasheet.
Therefore, it is difficult to improve the speed tracking and control performance of servo drive by using the traditional speed loop design method.
