MITSUBISHI general purpose AC servo amplifier MELSERVO-J2-Super series.
Rated output: 0.2kw.
Universal interface.
Voltage: single phase AC100V.
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 MR-J4-11KB datasheet PDF catalog MR-J4-11KB PDF datasheet MR-J4-11KB
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.Power: 75kw.
Voltage: 200V.
Sine wave filter.
The voltage and current of the motor can be adjusted to a sine wave.
The sine wave filter is installed to the output terminal of the inverter MR-J4-11KB datasheet PDF catalog MR-J4-11KB PDF datasheet.
Applicable to FR-A820-03800 (75K) above and FR-A840-02160 (75K) and above frequency converter.
Sine wave filter is equivalent to the operational characteristics of the sine wave power driver, can provide the following benefits.
Low noise.
No surge current.
Reduce motor loss (standard motor). The length of the line: 10m.
IP level: IP67.
Bending life: standard MR-J4-11KB datasheet PDF catalog MR-J4-11KB PDF datasheet.
Encoder cable for HF-KP/HF-MP/HF-SP/HF-JP/HC-LP/HC-UP series. Drive: MR-H_ACN series built-in positioning function.
Rated output: 0.1KW.
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, limiting the minimum detectable speed. MR-J4-11KB datasheet PDF catalog MR-J4-11KB PDF 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 larrger MR-J4-11KB datasheet PDF catalog MR-J4-11KB PDF datasheet.
Therefore, it is difficult to improve the speed tracking and control performance of servo drive by using the traditional speed loop design method.
