MITSUBISHI MR-J3-70T INSTRUCTION MANUAL MR-J3-70T CC-Link Manual

Drive: MR-H_ACN series CC-LINK features.
Rated output: 0.4KW.
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-J3-70T INSTRUCTION MANUAL.
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-J3-70T 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-J3-70T INSTRUCTION MANUAL.
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. The length of the line: 2M.
IP level: IP65.
Relay type MR-J3-70T INSTRUCTION MANUAL.
Bending life: standard.
The cable is not shielded.
Electric motor power supply cable (motor side), for HF-KP/HF-MP series (motor shaft with side extraction). MITSUBISHI motor universal AC servo amplifier MELSERVO-J3 series.
Rated output: 3.5kw.
Interface type: SSCNET type III fiber communication.
Full closed loop control.
Power specification: three phase AC400V.
High precision and high response location control.
Full closed loop control can be realized by double feedback control method.
Dual feedback control can be performed between the servo motor encoder and the load side encoder.
MR-J3-B-RJ006 can be used in conjunction with a number of manufacturers of linear encoder,
Users can build the system according to their own accuracy requirements. ABS type linear encoder using serial interface,
No need to install the battery on the servo amplifier can easily build the absolute position detection system.
Flexible system configuration.
Can achieve higher load side positioning accuracy!Drive: MR-H_ACN series built-in positioning function.
Rated output: 0.4KW.
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 pulsee, limiting the minimum detectable speed MR-J3-70T Manual.
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-J3-70T Manual.
Therefore, it is difficult to improve the speed tracking and control performance of servo drive by using the traditional speed loop design method.
