Adopting adaptive vibration control and reducing vibration MR-J3-70B PDF.
With a computer combination, using the software to achieve the best tuning MR-J3-70B
Pulse sequence input (position, speed control), analog input (speed, torque control) two purposes.
Simple operation.
The socket is arranged on the front panel, and is convenient to connect.
Using the socket, wiring easy.
Setting method and J2Super with interchangeable. Drive: MR-H_ACN series SSC-NET compatible AC servo MR-J3-70B PDF.
Rated output: 0.2KW.
The servo controller can easily transfer the operation module and the field bus module through the automation interface,
At the same time using different fieldbus modules to achieve different control modes (RS485, RS232, optical fiber, InterBus, ProfiBus),
And the control mode of general inverter is single.
The servo controller is directly connected with a rotary transformer or an encoder, which forms a closed loop of speed and displacement control MR-J3-70B PDF.
The general inverter can only form an open loop control system.
Servo controller of the control parameters (such as steady-state accuracy and dynamic performance) is better than the general inverter. Drive: MR-H_ACN series built-in positioning function.
Rated output: 7.0KW.
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 pulse, llimiting the minimum detectable speed MR-J3-70B datasheet.
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-J3-70B datasheet.
Therefore, it is difficult to improve the speed tracking and control performance of servo drive by using the traditional speed loop design method.
