MITSUBISHI motor universal AC servo amplifier MELSERVO-J3 series.
Rated output: 1.0kw.
Interface type: SSCNET type III fiber communication.
Full closed loop control.
Power specification: three phase AC400V.
High precision and high response location control.
Full closed loop control can be realized by double feedback control method.
Dual feedback control can be performed between the servo motor encoder and the load side encoder.
MR-J3-B-RJ006 can be used in conjunction with a number of manufacturers of linear encoder,
Users can build the system according to their own accuracy requirements. ABS type linear encoder using serial interface,
No need to install the battery on the servo amplifier can easily build the absolute position detection system.
Flexible system configuration.
Servo motor series: low inertia, medium / high power.
Rated output: 0.75kw.
Rated speed: 3000r/min.
Electromagnetic brake: with.
Shaft end specification: Standard (straight axis).
Features: low inertia for high speed / acceleration and deceleration operation occasions.
IP level: IP67.
Application example:
1, food processing machinery MR-J3-100B4-RJ006 MITSUBISHI.
2, printing machine.
3, injection molding machine (11KW, 15KW)
MR-J3-100B4-RJ006
4, large press machine (11KW, 15KW).
The protection level of the HF-SP/HF-JP series servo motor is IP67 (except the shaft part).
Low inertia of the power servo motor (0.5kW ~ 9kW), the maximum speed: 6000r/min (rated speed: 3000r/min),
Suitable for high frequency positioning and acceleration / deceleration operations, especially for food processing machines and printing machines MR-J3-100B4-RJ006 MITSUBISHI.
Low inertia, high power, no cooling fan servo motor (11kW and 15kW), maximum speed: 3000r/min (rated speed: 1500r/min).
The motor structure is more compact due to the adoption of the non cooling fan design, and the connection is reduced by using the power source connector.
(compared with the HF-LP series servo motor with the same power, the volume is reduced by about 46%, and the weight is reduced by about 34%,
Suitable for high frequency positioning and acceleration / deceleration operations, especially for injection molding machines and large presses MR-J3-100B4-RJ006 MITSUBISHI.
HF-JP703 (4) /903 (4) maximum speed: 5000r/min. Drive: MR-H_ACN series built-in positioning function.
Rated output: 1.0KW.
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,, limiting the minimum detectable speed MR-J3-100B4-RJ006.
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-J3-100B4-RJ006.
Therefore, it is difficult to improve the speed tracking and control performance of servo drive by using the traditional speed loop design method.
