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,
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 larger.
Therefore, it is difficult to improve the speed tracking and control performance of servo drive by using the traditional speed loop design method.

Rated output: 37kw.
Interface type: SSCNET type III fiber communication.
Special features: integrated driver security.
Power specification: three phase AC400V MR-H20ACN.
High speed serial communication between the SSCNET and the servo amplifier by using the fastest up to 0
MR-H20ACN44ms communication cycle,
A fully synchronous control system can be constructed.
It is only necessary to insert the special optical fiber into the joint to form SSCNET III network, which greatly reduces the wiring work and reduces the possibility of false wiring.
Due to the adoption of the optical fiber communication, the anti noise ability can be greatly improved and the long distance wiring of 50 meters (maximum 800 meters x 16 axes) can be realized MR-H20ACN.

Complete synchronization system with SSCNET high speed serial communication,
The communication cycle between the controller and the servo amplifier is the longest 0.888ms.
Such systems will be able to provide high reliability and high performance.
When connecting the servo system with SSCNET,
In the motion system, the parameters of the servo amplifier and the acquisition of the data will be displayed on the motion controller.
Connect a dedicated cable with an amplifier and a controller to form a SSCNET system.
This simple coonnection method reduces the routing time and helps to prevent noise MR-H20ACN.
Even in the MELSERVO-J2-SUPER series products using high resolution coding standards, the command frequency is no limit.
It is only necessary to add a battery on the serrvo amplifier, which can form the absolute value system MR-H20ACN.
Currently there are more than 1000000 high reliability SSCNET servo amplifier networks in use.
