MELSERVO-J4 Solutions For your all production needs
Offering theBest Solution
The MR-J4 series servo amplifiers can calculate power consumption itselfwithout a power measuring instrument, and can send the data to controllers for monitoring.
The multi-axis servo amplifier can store regenerative energy when motors decelerate.Those regenerative energy is used to drive another motor, contributing to energy conservation of the machine.In this system, the regenerative energy from the Y-axis is used to accelerate the Z-axis.
The "Capacity selection software" (free software) selects a suitable rotary servo motor, linear servo motor, and direct drive motor for your machine using various data, such as mass of the table and the load, the operation pattern, etc. After the selection, it shows the calculation process and results.

Energy-conservation Achieved by LM-H3 Linear Servo Motor SeriesEnergy Saving
Optimal Energy-conservative Machine SystemEnergy Saving
Increases power efficiency
Increases motorefficiency
PN Bus Voltage Connection +Power Regeneration Common Converter
For LM-H3, widths of the motor coil and the magnet are reduced by 10% from the prior model. Increased thrust to current ratio results in using the servo amplifier in smaller capacity,contributing to more compact machine(the reduction of materials).
Space Saving
LM-H3 has achieved a reduction of 25% in motor driving current due to a new magnetic design with optimized magnet form, contributing to power conservation for machines. The motor coil is lighter as compared to the prior model, which also contributes to saving energy for driving the moving part.
Reduced Energy Loss of Servo Amplifier and Servo Motor
Efficiency is increasedby the use of a newpower module.

Regenerative energy is used efficiently when multipleservo amplifiers and inverters are connected throughcommon PN bus to the power regeneration commonconverter.
* System only with common PN bus connection is also possible to beconfigured without using the power regeneration common converter.However, there are restrictions depending on the system. Contact yourlocal sales office for more details.* Refer to MR-J4-B(-RJ)/A(-RJ) Servo Amplifier Instruction Manual for selection of power regeneration common converter FR-CV series.
* For 720 N rated linear servo motor.
Thanks to the drivingsystem configured by servoamplifier and servo motorwith industry-leading levelof high performance,machine tact time andoperation time are reduced,achievingenergy-conservation.
