MITSUBISHI MR-J4-11KB4 Product information and technical parameters:
Brand: MITSUBISHI
Name: Servo driver
Model: MR-J4-11KB4
1 axis servo amplifier.
MITSUBISHI general AC servo amplifier MELSERVO-J4 series.
Rated output: 11.0kw.
Interface: SSCNET III /H.
Power supply: three phase AC400V.
0.6kW and 1kW above the servo amplifier.
Servo amplifier supporting SSCNET III /H.
Complete synchronization system capable of using high speed serial optical communication.
Can be combined with the servo system controller to maximize the performance of the servo system.
Improve mechanical properties by high performance motor.
By improving the resolution and processing speed of the encoder,
The rotating servo motor has higher precision and better performance of rotation.
Only open a key type of adjustment function, can be carried out including mechanical resonance filter, high end seismic control II, low pass filter servo gain adjustment.
Easily start advanced seismic function, it can maximize the mechanical properties.
It can automatically adjust the required response settings automatically.

Drive: MR-H_ACN series SSC-NET compatible AC servo.
Rated output: 5.0KW.
The servo controller can easily transfer the operation module and the field bus module through the automation interface,
At the same time using different fieldbus modules to achieve different control modes (RS485, RS232, optical fiber, InterBus, ProfiBus),
And the control mode of general inverter is single MR-J4-11KB4.
The servo controller is directly connected with a rotary transformer or an encoder, which forms a closed loop of speed and displacement control MR-J4-11KB4
The general inverter can only form an open loop control system.
Servo controller of the control parameters (such as steady-state accuracy and dynamic performance) is better than the general inverter MR-J4-11KB4. 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-J4-11KB4.
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 larger.
Therefore, it is difficult to improve the speed tracking and control performance of servo drive by using the traditional speed loop design method.Drive: MR-H_AN series.
Rated output: 0.2KW.
Universal AC servo.
Servo driver (drives servo) also known as the "servo controller", "servo amplifier",
Is a kind of controller used to control the servo motor. Its function is similar to that of the frequency converter,
Belongs to a part of the servo system, which is mainly used in high precision positioning system.
In general, the servo motor is controlled by position, speed and torque in three ways,
To achieve high precision positioning of the transmission system, the current transmission technology is the high-end products.
Servo drive is an important part of modern motion control,
Is widely used in industrial robots and CNC machining centers and other automation equipment.
In particular, it has become a hot ressearch topic in the field of servo drives for the control of AC permanent magnet synchronous motor MR-J4-11KB4.
Current, speed and position 3 closed loop control algorithm based on vector control is widely used in AC servo drive system.
The speed cllosed-loop design of the algorithm is reasonable or not, for the entire servo control system,
Especially the speed control performance plays a key role MR-J4-11KB4.
