SINUMERIK Ctrl-Energy - Improved energy efficiency

As technology leader in the field of CNC engineering, Siemens can offer functions which are not only technologically advanced, but which are also designed to boost the energy efficiency of the machine. The SINUMERIK Ctrl-Energy portfolio includes an extensive range of energy-efficient systems, solutions and services.

Ctrl-E Analysis

Using the Ctrl-E Analysis function, SINUMERIK CNCs acquire not only the energy consumption of the drive system, but also the energy consumption of the entire machine. This makes it possible for the machine user to analyze the energy consumption per workpiece and to subsequently devise an optimized machining strategy. With the Ctrl+E shortcut, the machine operator can visualize energy consumption at the touch of a button.

Visualization of energy consumption

Dynamic energy management

SINAMICS S120 drive systems are designed to allow dynamic energy management in the DC link and are capable of highly efficient regenerative feedback. This means that energy produced during braking is not converted to heat by braking resistors, but stored first in the DC link so that it can be recovered to the grid. Moreover, drive axes can be optionally utilized as kinetic energy stores with the result that all energy stays within the drive system with virtually no losses.

Ctrl-E Profiles

Ctrl-E Profiles gives the machine manufacturer a configuring platform for controlling the energy-saving modes of the machine. This means that specific energy consumers can be shut down when the machine is idle. With the Ctrl+E shortcut, the operator can quickly and easily influence the energy-saving modes.

Flux reduction and reactive power compensation

SINAMICS S120 drive systems allow automatic flux reduction during partial-load operation of asynchronous spindles, thereby resulting in a reduction of unnecessary heat losses. Intelligent Active Line infeed/regenerative feedback modules can be used to fully compensate the machine's reactive power, so making it unnecessary to install costly, high-loss reactive power compensation equipment.
