Motor aspects: the material, structure and processing technology of the servo motor is much higher than that of AC motor,
That is when the driver output current, voltage, frequency change is fast power supply,
The servo motor can change according to the change of the response of the power supply,
Response characteristics and anti overload capacity is much higher than the AC motor drive,
Motor aspects of the serious differences between the two are fundamentally different performance MITSUBISHI MR-J2S-700A4 MITSUBISHI MR-J2S-700A4

That is not the inverter output can not change so fast power signal,
But the motor itself can not react,
So in the frequency of the internal algorithm set to protect the motor to do the corresponding overload.
Of course, even without the ability to set the output of the inverter is limited,
Some of the excellent performance of the inverter can be directly driven servo motor MITSUBISHI MR-J2S-700A4. 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.
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 ppulse, limiting the minimum detectable speed MR-J2S-700A4.
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-J2S-700A4.
Therefore, it is difficult to improve the speed tracking and control performance of servo drive by using the traditional speed loop design method.
