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. Contributing Energy Conservation Using Regenerative Energy Regenerative energy is temporarily stored to be used as driving power energy. When Y-axis decelerates, Z-axis accelerates.

However, there are restrictions depending on the system. Contact your local 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.

Advanced Function and Performance for More Energy-conservation Reduced Energy Loss of Servo Amplifier and Servo Motor < Servo amplifier > Increases power efficiency Efficiency is increased by the use of a new power module. Increases motor efficiency < Servo motor > Motor efficiency is increased by optimized design of magnetic circuit. Energy Saving FR-A700 Tension detector Servo motor Energy Saving FR-A700 Energy-conservation Due to the Improved Machine Performance Thanks to the driving system configured by servo amplifier and servo motor with industry-leading level of high performance, machine tact time and operation time are reduced, achieving energy-conservation. Reduced machine operation time Energy-conservation Achieved by LM-H3 Linear Servo Motor Series Reduced Motor Driving Power 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. 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). * For 720 N rated linear servo motor.
