MR-J2M multi axis servo amplifier drive unit.
Rated output: 0.1kw.
Servo system is used to achieve the following purposes:
1, with a small power command signal to control the power load MR-C10A PDF. Gun control and rudder control is a typical example.
2, in the absence of mechanical connection, the input shaft control is located in the distance of the output shaft, to achieve remote synchronous transmission MR-C10A
3, so that the output of the mechanical displacement of the precise tracking of electrical signals, such as records and instructions, etc.. MITSUBISHI general purpose AC servo amplifier MELSERVO-J2-Super series MR-C10A PDF.
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 MR-C10A PDF.
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 MITSUBISHI Instruction manual.
Even in the MELSERVO-J2-SUPER series products using high resolution coding standards, the command freequency is no limit MR-C10A Manual.
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 MITSUBISHI Instruction manual. The length of the line: 30M.
Relay type.
IP level: IP20.
Bending life: high bending life.
Encoder with cable (amplifier side); for HF-KP/HF-MP series. Drive: MR-H_ACN series built-in positioning function MITSUBISHI Instruction manual.
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 pullse, limiting the minimum detectable speed MR-C10A 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-C10A Manual.
Therefore, it is difficult to improve the speed tracking and control performance of servo drive by using the traditional speed loop design method.
