Energy-conservation with Common DC Bus Connection

When multiple servo amplifiers and drive units are connected to the MR-CV power regeneration converter unit by a common DC bus connection, the regenerative power of one axis is used for driving other axes, contributing to energy-conservation. The multi-axis servo amplifier has the same effect.

Further Energy-conservation with Power Regeneration System

The MR-CV power regeneration converter unit has a power regeneration system which returns the regenerative power back to the power supply, enabling the regenerative power to be used for other systems for further energy-conservation. In addition, when the MR-CV power regeneration converter unit is used, a regenerative option is not required, and thus, the total heat generation in a system will be decreased.

Less heat generation due to elimination of regenerative option

Advanced Function and Performance for More Energy-conservation

The servo amplifiers and the servo motors with the industry-leading level of high performance reduce machine cycle time and operation time, resulting less energy consumption. Energy-conservation due to the improved machine performance Reduced machine operation time

Reduced energy loss of servo amplifier and servo motor

[Servo amplifier] Efficiency is increased by the use of a new power module. [Servo motor] Motor efficiency is increased by optimized design of magnetic circuit.

Reduced loss
