MR-J3-40B MRJ340B MITSUBISHI Servo Driver 400W 200V

Product Details

The Mitsubishi MELSERVO-J3 series general-purpose AC servo has further higher performance and higher functions compared to the current MELSERVO-J2-Super series.The MR-J3-B servo amplifier connects to servo system controller and others via high speed synchronous network and operates by directly reading position data. The rotation speed/direction control of servo motor and the high accuracy positioning are executed with the data from command module. SSCNET equipped by theMR-J3-B servo amplifier greatly improved its communication speed and noise tolerance by adopting optical communication system compared to the current SSCNET. For wiring distance, 50m of the maximum distance between electrodes is also offered.The torque limit with clamping circuit is put on the servo amplifier in order to protect the power transistor of main circuit from the over current caused by rapid acceleration/deceleration or overload. In addition, torque limit value can be changed to desired value with parameter.

Specifications

Voltage/frequency: 3-phase or 1-phase 200 to 230VAC, 50/60Hz

Permissible voltage fluctuation: 3-phase or 1-phase 200 to 230VAC: 170 to 253VAC

Permissible frequency fluctuation: Within 5%

Power supply capacity: Refer to section 10.2

Inrush current: Refer to section 10.5

Control System: Sine-wave PWM control, current control system

Protective functions: Overcurrent shut-off, regenerative over voltage shut-off, overload shut-off (electronic thermal relay),servo motor overheat protection, encoder error protection, regenerative error protection,undervoltage, instantaneous power failure protection, overspeed protection, excessive error protection.

Function

High-resolution encoder: High-resolution encoder of 262144 pulses/rev is used as a servo motor encoder.

Low-pass filter: Suppresses high-frequency resonance which occurs as servo system response is increased.

Machine simulation: Can simulate machine motions on a personal computer screen on the basis of the machine analyzer results.MR Configurator is necessary for this function.

Slight vibration suppression contro: Suppresses vibration of 1 pulse produced at a servo motor stop

Auto tuning: Automatically adjusts the gain to optimum value if load applied to the servomotor shaft varies. Higher in performance than MR-J2-Super series servo amplifier.

Brake until: Used when the regenerative option cannot provide enough regenerative power.Can be used the 5kW or more servo amplifier.

POWER INDUSTRY

Hydropower industry with power industry capabilities.
The working power of the remote I/O is provided by the corresponding LCU to the unit local control unit (LCU1, LCU2, LCU3, LCU4).
The LCU should provide an RS-485 serial interface, using the Modbus (Master and Slave) standard communication protocol interface.
Molex is used for gateway protocol conversion. The module is directly plugged into AB's 1756 rack and has standard blocks for programming.
The international standard industrial Ethernet protocol EtherNet/IP is used between the PLC and the workstation in the LCU.
The communication speed reaches 100Mbps, and the PLC adopts AB ControlLogix system governor oil pump control loop and ball valve control loop to enter the unit's local LCU control.
