– Energy efficiency in servo applications
Features
The crucial part of energy-efficient operation of servo drive technology is the detailed planning and
fulfillment of process and efficiency requirements. With the energy efficiency concept effiDRIVE
®
for
servo applications, SEW-EURODRIVE offers comprehensive consulting during the planning of new
plants and the modernization of existing systems. With our great expertise regarding drive tech-
nology and the industry, we focus on efficiency already during the first steps of selecting the used
technology and products in order to optimize the energy consumption. But it is not sufficient to only
combine energy-efficient components. Only looking at the application in its entirety allows for the
maximum energy efficiency.
Energy-efficient components
Sine-shaped regenerative power supply
modules
MXR80A
–
In regenerative operating states, the braking energy is fed back into the supply system
–
Energy supply and energy recovery are sinusoidal with cos
I
= 1
–
Almost complete avoidance of supply harmonics
–
No interference of sensitive electronic devices in direct vicinity
–
Determination of energy flow, detailed diagnostic information
–
Controlled DC link voltage independent of link voltage
Block-shaped regenerative power supply
modules
MXR81A
–
In regenerative operating states, the braking energy is fed back into the supply system
–
Inexpensive alternative to sinusoidal regenerative power supply if the supply system conditions
are stable
–
Automatic deactivation of the recovery during motoring operation
–
Emergency braking resistor can be connected
Capacitor module
MXC80A
–
DC link energy is absorbed or supplied with up to 50 kW
–
Up to 1000 W can be stored in the module
–
The module is charged actively via charging connection
–
With adequate project planning, the braking energy can be completely recycled for the next
travel task
–
There is no need for braking resistors
–
Especially suited for cycles with small drives
Compact power supply module
MXP81A
–
Combination of 10 kW power supply module and 250 W capacitor module
–
Especially cost-effective and space-saving with small systems
–
Size-optimized braking resistor is already integrated in the module
