MITSUBISHI motor universal AC servo amplifier MELSERVO-J3 series.
Rated output: 1.0kw.
Interface type: SSCNET type III fiber communication.
Power specification: three phase AC400V.
High speed serial communication between the SSCNET and the servo amplifier by using the fastest up to 0.44ms communication cycle,
A fully synchronous control system can be constructed M700V/M70V Series Manual M700V/M70V Series INSTRUCTION MANUAL M700V/M70V Series
It is only necessary to insert the special optical fiber into the joint to form SSCNET III network, which greatly reduces the wiring work and reduces the possibility of false wiring.
Due to the adoption of the optical fiber communication, the anti noise ability can be greatly improved and the long distance wiring of 50 meters (maximum 800 meters x 16 axes) can be realized M700V/M70V Series Manual M700V/M70V Series INSTRUCTION MANUAL.
A servo amplifier to meet the full closed loop control function MR-J3-B-RJ006.
Suitable for mechanical servo optimization and adjustment!
More advanced optimization adjustment function and control function to maximize mechanical properties. Drive: MR-H_ACN series built-in positioning function.
Rated output: 3.5KW.
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 M700V/M70V Series Manual M700V/M70V Series INSTRUCTION MANUAL.
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, limiting the minimum detectable speed.
2 conntrol 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 M700V/M70V Series Manual M700V/M70V Series INSTRUCTION MANUAL M700V/M70V Series Manual M700V/M70V Series INSTRUCTION MANUAL.
Therefore, it is difficult to improve the speed tracking and control performance of servo drive by using the traditional speed loop design method.
