MR-J2-20A1 MITSUBISHI MR-J2-20A1 Electric machinery

Brand: MITSUBISHI
Name: Universal interface driver
Model: MR-J2-20A1
MITSUBISHI general purpose AC servo amplifier MR-J2 series.
Rated output: 0.2kw.
Interface: general purpose interface.
Voltage: single phase AC100V.
MITSUBISHI servo system in the MITSUBISHI servo amplifier is widely used,
It can not only be used in the high precision position control and speed control of the working machinery and general industrial machinery,
Can also be used in the field of speed control and tension control.
By installing a personal computer with a servo setting software, the parameters setting, trial run, state display, and gain adjustment are performed.
MITSUBISHI servo system MR-J2S column is developed on the basis of the servo MR-J2 series with a higher performance and more features of the MITSUBISHI servo system,
The control modes are position control, speed control and torque control, as well as the switching control mode among them.

Servo motor series: flat type, medium power.
Rated output: 2.0kw.
Rated speed: 2000r/min.
Electromagnetic brake: No.
Shaft end specification: Standard (straight axis).
Features: flat type of the model is very suitable for servo motor installation space is limited occasions.
IP level: IP65.
Application example:
1, industrial robots MITSUBISHI MR-J2-20A1.
2, food processing machinery.
Abundant motor product line can optimize the performance of the machine MR-J2-20A1
Has a rich motor product line including a rotary servo motor, linear servo motor and direct drive motor. Servo motor series: low inertia, small capacity.
Rated output: 0.2kw.
Rated speed: 3000r/min.
Electromagnetic brake: incidental.
Oil seal: incidental (Note 1, note 2, note 3) MITSUBISHI MR-J2-20A1.
Power supply: 200V.
Note 1 through HG-KR and HG-MR series 0.1kW and HG-SR series can be supported.
Note 2 with the speed reducer case, do not configure the oil seal.
Note 3 with oil seal HG-KR, HG-MR series servo motor''s appearance size standard is different.
The rated speed is 3000r/min, the maximum speed is 6000r/min.
The maximum torque of 350% of the rated torque, high torque in the field of high rotation, only to support the HG-KR series products MITSUBISHI MR-J2-20A1.
Built in absolute position encoder with high resolution.
Standard high resolution absolute position encoder (4194304p/rev (22bit)).
To achieve a higher accuracy of the positioning function MITSUBISHI Electric machinery.
Improve the environmental performance of HG-KR, HG-MR, HG-RR, HG-UR series of products using IP65. Drive: MR-H_ACN series built-in positioning function MITSUBISHI Electric machinery.
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 MITSUBISHI Electric machinery.
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, liimiting the minimum detectable speed MR-J2-20A1.
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 larrger MITSUBISHI MR-J2-20A1.
Therefore, it is difficult to improve the speed tracking and control performance of servo drive by using the traditional speed loop design method.
