"MITSUBISHI general purpose AC servo amplifier MELSERVO-J2-Super series.
Rated output: 0.2kw.
SSCNET interface.
Voltage: 3 phase AC200VAC or single phase AC230V.
The communication cycle between the controller and the servo amplifier is the longest 0.888ms.
Such systems will be able to provide high reliability and high performance.
In the motion system, the parameters of the servo amplifier and the acquisition of the data will be displayed on the motion controller.
Connect a dedicated cable with an amplifier and a controller to form a SSCNET system.
This simple connection method reduces the routing time and helps to prevent noise.
Even in the MELSERVO-J2-SUPER series products using high resolution coding standards, the command frequency is no limit.
It is only necessary to add a battery on the servo amplifier, which can form the absolute value system.
Currently there are more than 1000000 high reliability SSCNET servo amplifier networks in use. "
Type: HC-PQ type.
Output power: 0.03kw.
Rated speed: 3000r/min.
Electromagnetic brake: No.
Key axis: D type shaft.
Motor aspects: the material, structure and processing technology of the servo motor is much higher than that of AC motor,
That is when the driver output current, voltage, frequency change is fast power supply,
The servo motor can change according to the change of the response of the power supply,
Response characteristics and anti overload capacity is much higher than the AC motor drive,
Motor aspects of the serious differences between the two are fundamentally different performance MR-J2S-20B
MR-J2S-20B
That is not the inverter output can not change so fast power signal,
But the motor itself can not react,
So in the frequency of the internal algorithm set to protect the motor to do the corresponding overload MR-J2S-20B.
Of course, even without the ability to set the output of the inverter is limited,
Some of the excellent performance of the inverter can be directly driven servo motor. Drive: MR-H_ACN series CC-LINK features.
Rated output: 15KW.
The test system is composed of two parts, namely, the servo driver, the motor system and the host computer MR-J2S-20B.
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 voolume,
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-J2S-20B.
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-J2S-20B.
