Drive: MR-H_ACN series built-in positioning function.
Rated output: 15KW.
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 MR-J4-200A4 PDF
MR-J4-200A4
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-J4-200A4 PDF.
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. MITSUBISHI general purpose AC servo amplifier MELSERVO-J2-Super series MR-J4-200A4 PDF.
Rated output: 5.0kw.
Built in positioning function.
Voltage: 3 phase AC200VAC or single phase AC230V.
Super function, excellent performance.
High performance CPU integration, greatly improve product responsiveness.
Due to the application of high performance CPU, so that the response can be greatly improved.
Speed loop frequency response increased to more than 550HZ.
MR-J2-Super series is the best device for high speed positioning applications.
Easy adjustment.
Model adaptive control / advanced real time automatic tuning. MR-J2M multi axis servo amplifier expansion unit.
1, the servo controller through the automation interface can be easily carried out the operation module and the conversion of the field bus module,
At the same time using different fieldbus modules to achieve different control modes (RS485, RS232, optical fiber, InterBus, ProfiBus),
And the control moode of general inverter is single MR-J4-200A4 datasheet.
2, the servo controller is directly connected with the rotary transformer or encoder, and the speed and displacement control loop is formed.
The general inverter can only form an open loop conntrol system MR-J4-200A4 datasheet.
3 servo controller of the control parameters (such as steady-state accuracy and dynamic performance) is better than the general inverter.
