Drive: MR-H_ACN series built-in positioning function.
Rated output: 0.1KW.
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 MR-J2-3500B Manual MR-J2-3500B Specifications and Installation Guide MR-J2-3500B
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 MR-J2-3500B Manual MR-J2-3500B Specifications and Installation Guide.
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.MITSUBISHI general purpose AC servo amplifier MELSERVO-J2-Super series MR-J2-3500B Manual MR-J2-3500B Specifications and Installation Guide.
Rated output: 30.0kw.
SSCNET interface.
Voltage: 3 phase AC400V.
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 connection method reduces the routing time and helps to preveent noise MR-J2-3500B Manual MR-J2-3500B Specifications and Installation Guide.
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 seervo amplifier, which can form the absolute value system MR-J2-3500B Manual MR-J2-3500B Specifications and Installation Guide.
Currently there are more than 1000000 high reliability SSCNET servo amplifier networks in use.
