MITSUBISHI MR-H200AN PDF catalog MR-H200AN datasheet PDF datasheet

Drive: MR-H_ACN series CC-LINK features.
Rated output: 11KW.
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 MR-H200AN PDF datasheet.
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-H200AN 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 MR-H200AN PDF datasheet.
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 unit.

Function of switching amplitude. The increase in the process of switching and stopping,
And in the operation of the use of the switching signal, switching growth. Drive: MR-H_ACN series built-in positioning function.
Rated output: 0.6KW.
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, limmiting the minimum detectable speed MR-H200AN PDF catalog.
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-H200AN 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.
