MITSUBISHI general purpose AC servo amplifier MR-J2 series.
Rated output: 0.4kw.
Interface: general purpose interface.
Voltage: single phase AC200V.
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 MR-J3-20B1-RJ006 PDF catalog MR-J3-20B1-RJ006
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 MR-J3-20B1-RJ006 PDF catalog . Power: 75kw.
Voltage: 200V.
Sine wave filter.
The voltage and current of the motor can be adjusted to a sine wave.
The sine wave filter is installed to the output terminal of the inverter.
Applicable to FR-A820-03800 (75K) above and FR-A840-02160 (75K) and above frequency converter MR-J3-20B1-RJ006 PDF catalog .
Sine wave filter is equivalent to the operational characteristics of the sine wave power driver, can provide the following benefits.
Low noise.
No surge current.
Reduce motor loss (standard motor). Drive: MR-H_ACN series built-in positioning function MITSUBISHI MR-J3-20B1-RJ006 PDF datasheet.
Rated output: 2.0KW.
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 MITSUBISHI MR-J3-20B1-RJ006 PDF datasheet.
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 MR-J3-20B1-RJ006 PDF datasheet.
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 thhe minimum detectable speed MR-J3-20B1-RJ006 datasheet.
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-J3-20B1-RJ006 PDF catalog .
Therefore, it is difficult to improve the speed tracking and control performance of servo drive by using the traditional speed loop design method.
