Driving power and regenerative energy are calculated from the data in the servo amplifier such as speed and current.
Motor current value, power consumption, and total power consumption are monitored with MR Configurator2. In SSCNET III/H
system, data are transmitted to a Motion controller, and the power consumption is analyzed and displayed.
In the multi-axis servo amplifier, the
regenerative energy of an axis is used as
driving power energy for the other axes,
contributing to energy-conservation of
machine. Reusable regenerative energy
stored in the capacitor is increased in
MR-J4W_ as compared to the prior model.
Regenerative option is no longer required.

* Regenerative resistor may be required depending on the
conditions.
* In the multi-axis servo amplifier, the amount of temporarily
stored regenerative energy can be increased by using a
capacitor bank. (Available in the future)

Efficiency is increased
by the use of a new
power module.
[Servo motor]
Motor efficiency is
increased by optimized
design of magnetic
circuit.
Regenerative energy is used efficiently when multiple
servo amplifiers and inverters are connected through
common PN bus to the power regeneration common
converter.
* System only with common PN bus connection is also possible to be
configured without using the power regeneration common converter.
However, there are restrictions depending on the system. Contact your
local sales office for more details.
* Refer to MR-J4-B/A Servo Amplifier Instruction Manual for selection of
power regenerative common converter FR-CV series.

LM-H3 series achieves reduction of motor driving power due
to optimized magnet form and new magnetic design by 25%*.
Conservation of power is achieved for machine. As compared
to the prior model, the motor coil is lighter by approximately
12%*. The energy required to drive the moving part is
reduced.
* For 720 N rated linear servo motor.
Energy-conservation achieved by LM-H3 linear servo motor series
Reduced motor driving power
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
The new environment-friendly HG
rotary servo motor series uses 30%
less permanent magnet than the
prior HF series due to the optimized
design of magnetic circuit. The total
mass is also reduced.
* For HG-KR43.
Contribution to resource-saving
Reduced energy loss of servo amplifier and servo motor
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.
