The rotor of the servo motor is a permanent magnet, which is controlled by the U/V/W,
The rotor rotates under the action of the magnetic field, and the encoder feedback signal of the motor is given to the driver,
According to the feedback value and the target value, the driver adjusts the rotation angle of the rotor HA-LH22K2.
Accuracy of the servo motor depends on the accuracy of the encoder (number of lines). 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 encodeer pulse, limiting the minimum detectable speed HA-LH22K2.
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 HA-LH22K2.
Therefore, it is difficult to improve the speed tracking and control performance of servo drive by using the traditional speed loop design method.
