MITSUBISHI MR-J4-70B-RJ Product information and technical parameters:
Brand: MITSUBISHI
Name: Servo driver
Model: MR-J4-70B-RJ
1 axis servo amplifier.
MITSUBISHI general AC servo amplifier MELSERVO-J4 series.
Rated output: 0.75kw.
Interface: SSCNET III /H.
Power supply: three phase AC200V.
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 SSCNET III /H.
Complete synchronization system capable of using high speed serial optical communication.
Can be combined with the servo system controller to maximize the performance of the servo system.
2 low frequency vibration can be suppressed at the same time by supporting the seismic algorithm of 3 inertial equipment.
Configurator2 MR to achieve convenient adjustment.
Effectively restrain the low frequency aftershock effect produced by the front end of the boom or the main body of the device 100Hz.
Can effectively shorten the time to control the stability of the aftershock.
In the XY design of trajectory control, improve the accuracy of arc track.
At the same time, it can effectively control the phenomenon of quadrant protrusion caused by the rotation direction of the servo motor, which is caused by friction and twisting.

Drive: MR-H_ACN series SSC-NET compatible AC servo.
Rated output: 22KW.
The servo controller can easily transfer the operation module and the field bus module through the automation interface,
At the same time using different fieldbus modules to achieve different control modes (RS485, RS232, optical fiber, InterBus, ProfiBus),
And the control mode of general inverter is single MITSUBISHI MR-J4-70B-RJ MR-J4-70B-RJ
The servo controller is directly connected with a rotary transformer or an encoder, which forms a closed loop of speed and displacement control.
The general inverter can only form an open loop control system.
Servo controller of the control parameters (such as steady-state accuracy and dynamic performance) is better than the general inverter MITSUBISHI MR-J4-70B-RJ. 1 axis servo amplifier.
MITSUBISHI general AC servo amplifier MELSERVO-J4 series.
Rated output: 5.0kw.
Interface: General purpose.
Power supply: three phase AC200V.
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 MITSUBISHI MR-J4-70B-RJ.
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.
Improve mechanical properties by high performance motor.
By improving the resolution and processing speed of the encoder,
The rotating servo motor has higher precision and better performance of rotation.
Only open a key type of adjustment function, can be carried out including mechanical resonance filter, high end seismic control II, low pass filter servo gain adjustment.
Easily start advanced seismic function, it can maximize the mechanical properties.
