A set of power connectors for use in
HC-SFS702; 7024.
HA-LFS702.
For MR-J2S-11KA (4) MR-J2S-22KA to (4). Drive: MR-H_ACN series built-in positioning function.
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 MR-J4-22KB PDF catalog .
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-J4-22KB
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 MR-J4-22KB 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 larger.
Therefore, it is difficult to improve the speed tracking and control performance of servo drive by using the traditional speed loop design method MR-J4-22KB PDF catalog . Power: 220kw.
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 MITSUBISHI MR-J4-22KB PDF datasheet.
Applicable to FR-A820-03800 (75K) above and FR-A840-02160 (75K) and above frequency converter.
Sine wave filter is equivalent to the operational characteristics of the sine wave power driver, can provide the following benefits MITSUBISHI MR-J4-22KB PDF datasheet.
Low noise.
No surge current.
Reduce motor loss (standard motor). 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 MITSUBISHI MR-J4-22KB PDF datasheet.
The host computer sends the speed command signal to the servo driver,
Servo drives start to run in accordance with the instructions.
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. 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 thee 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-J4-22KB datasheet.
Usually, such testing system is only used to test the rotational speeed 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 MR-J4-22KB PDF catalog .
