MITSUBISHI MR-J2S-60B4 Product information and technical parameters:
Brand: MITSUBISHI
Name: SSCNET interface servo amplifier
Model: MR-J2S-60B4
MITSUBISHI general purpose AC servo amplifier MELSERVO-J2-Super series.
Rated output: 0.6kw.
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 prevent noise.
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 servo amplifier, which can form the absolute value system.
Currently there are more than 1000000 high reliability SSCNET servo amplifier networks in use.

Drive: MR-H_ACN series CC-LINK features.
Rated output: 0.2KW.
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-J2S-60B4.
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-J2S-60B4 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-J2S-60B4.
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. Drive: MR-H_ACN series built-in positioning function MITSUBISHI MR-J2S-60B4.
Rated output: 22KW.
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 MR-J2S-60B4.
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-60B4.
Therefore, it is difficult to improve the speed tracking and control performance of servo drive by using the traditional speed loop design method.
