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.
