MITSUBISHI MR-J4-20A-RJ Product information and technical parameters:
Brand: MITSUBISHI
Name: Servo driver
Model: MR-J4-20A-RJ
"1 axis servo amplifier.
MITSUBISHI general AC servo amplifier MELSERVO-J4 series.
Rated output: 0.2kw.
Interface: General purpose.
Power supply: three phase AC200V or single phase AC200V power supply.
Single phase AC200V is limited to 0.75kW following servo amplifier.
Special specification: full closed loop control 4 wire / device end encoder ABZ phase input corresponding support function security unit, support positioning mode.
Servo amplifier supporting universal interface.
Servo amplifier for universal interface.
Speed / torque control of position control and analog voltage command can be carried out by using pulse train command.
Support Max instruction pulse frequency 4 Mpulses/s.
Not only inherited the original product of high performance and high reliability, but also made a further improvement beyond imagination.
MELSERVO-J4 grand debut.
Servo market for the star of tomorrow. World class servo products.
The new generation of MELSERVO should be what kind of? The answer to this question is already floating
Out of the water. MELSERVO-J4, it represents the whole digital, the original high performance based on an evolutionary.
Is also fully meet the requirements of human beings and the environment MELSERVO latest masterpiece.
For example, the safety and environmental requirements for the safety of human use and the safety specifications and "to Use Easy" design.
To meet the needs of the environmental protection era of energy-saving performance.
Beyond the performance of the evolution of MELSERVO-J4, shocking debut! "

Drive unit.
MITSUBISHI universal AC servo amplifier MELSERVO-J4 series.
Rated output: 37kw.
Interface: SSCNET III /H.
Power supply: three phase AC200V.
Special specifications: full closed control 4 wire / support mechanical end encoder ABZ phase input / support positioning mode.
Support position control, speed control, torque control MR-J4-20A-RJ.
Position control to follow the position instructions MR-J4-20A-RJ
When the control is inserted, the position control is performed.
Speed control follows the speed command to control the speed within a certain range.
Torque control to follow the torque command to control the stable torque.
Function of switching amplitude. The increase in the process of switching and stopping,
And in the operation of the use of the switching signal, switching growth MR-J4-20A-RJ. Motor series: medium inertia, medium capacity.
Using a serial absolute / incremental encoder.
Rated output power: 7.0kw.
Rated speed: 2000rpm.
With a brake band.
Shaft end: straight shaft.
The rotor of AC servo motor is usually made of squirrel cage, but in order to make the servo motor has a wide range of speed regulation, linear mechanical properties,
Without the "rotation" phenomenon and the performance of the fast response, it is compared with the ordinary motor,
The two characteristics of rotor resistance and moment of inertia should be provided MR-J4-20A-RJ.
At present, there are two kinds of rotor structure, one is the squirrel cage rotor, which is made of conductive material with high resistivity,
In order to reduce the moment of inertia of the rotor, the rotor is slender.Servo motor series: low inertia, small capacity.
Rated output: 0.75kw.
Rated speed: 3000r/min.
Electromagnetic brake: incidental.
Oil seal: incidental (Note 1, note 2, note 3).
Power supply: 200V.
Note 1 through HG-KR and HG-MR series 0.1kW and HG-SR series can be supported.
Note 2 with the speed reducer case, do not configure the oil seal.
Note 3 with oil seal HG-KR, HG-MR series servo motor''s appearance size standard is different.
The rated speed is 3000r/min, the maximum speed is 6000r/min.
The maximum torque of 350% of the ratted torque, high torque in the field of high rotation, only to support the HG-KR series products MR-J4-20A-RJ.
Built in absolute position encoder with high resolution.
Standard high resolution absolute position encoder (4194304p/rev (22bit)).
To achhieve a higher accuracy of the positioning function MR-J4-20A-RJ.
Improve the environmental performance of HG-KR, HG-MR, HG-RR, HG-UR series of products using IP65.
