SIEMENS INTRODUCES SINUMERIK CTRL-ENERGY TO MAKEENERGY-EFFICIENT CNC MACHINES MORE ECONOMICAL AND PRODUCTIVE

CHICAGO, August 2, 2011 The topic of energy savings is increasingly gaining importance inthe machine tool industry because of the rising cost of energy, ever more stringent environmental

regulations and efforts to obtain certification according to the international energy efficiency standard

EN16001. According to a recent EU Commission report, industrial production accounted for 40 percent

of total power consumption in the EU-27 in 2007, of which 70 percent was used by electrical drive

systems. Depending on the company involved, machine tools can account for up to 68 percent of the

total energy requirement. This fact makes energy efficiency in manufacturing a decisive factor in

reducing plant costs and improving overall competitiveness. With this in mind, Siemens has carried out

an energy analysis of individual machine tool components with the goal of achieving significant cuts in

energy consumption through Sinumerik Ctrl-Energy.

With Sinumerik Ctrl-Energy, Siemens has opened up a broad range of solutions for the energy-

efficient operation of machine tools, encompassing its Sinamics drive systems and motors, CNC and

drive functions, PC software solutions and services. Sinumerik Ctrl-Energy offers energy-efficient

solutions covering every aspect of the machines lifecycle, starting from machine design and

engineering through machine operation and partial or complete retrofit. This makes Sinumerik Ctrl-

Energy a broad-based platform for efficient machine management, which will benefit both the machine

tool OEM and end-user.

CTRL-E FUNCTIONS FOR ENERGY MANAGEMENT

Using a simple Ctrl and E key combination on the operator panel, Sinumerik CNCs can

provide a fast evaluation of the machine tools energy consumption and also manage energy

consumption during machine downtime. Using the Ctrl-E Analysis function, Sinumerik controls

determine both the energy consumption of a drive system and the entire machine. They enable the

user to analyze the amount of energy that goes into machining every individual workpiece as the basis

for machining strategy improvements. The Ctrl-E Profiles function also provides a configuration

platform for the management of the machines energy saving modes, helping to selectively shut down

specific power loads during downtimes.

FREQUENCY CONVERTERS AND ENERGY-SAVING MOTORS THE INTEGRATED DRIVE

TRAIN AS A CORE ELEMENT OF OVERALL ENERGY EFFICIENCY

The Siemens Sinamics S120 drive system permits dynamic energy management in the DC link

and makes use of a highly efficient power recovery system, which initially stores generated braking

energy in a DC link and optionally feeds it back into the grid rather than allowing the brake resistance to

turn it into heat. Sinamics drives and Siemens motors have been designed with a clear focus on

energy efficiency aspects. In this manner, integrated drive modules from Siemens reach a high

efficiency rating of 9799 percent.

With an efficiency of up to 94 percent in synchronous motors and up to 91 percent in

asynchronous motors, the Siemens motor range also provides a basis for energy-efficient machine

designs. In a typical machine tool, auxiliary assemblies such as hydraulic supply systems or cooling

and lubrication units account for over half the total energy consumption. Energy-saving 1LE standard

asynchronous motors have an efficiency rating of up to 97 percent and offer significant potential forauxiliary assembly improvement. The use of Sinamics G120 frequency converters helps adjust the

speed and also the energy consumption of auxiliary systems to the level required at each stage of

the process.

POTENTIAL SAVINGS: CURRENT FLOW REDUCTION AND POWER FACTOR COMPENSATION

Sinamics S120 drive systems permit automatic current flow reduction in asynchronous spindles

operating under part-load, avoiding unnecessary heat loss. The reactive power of a machine can be

fully compensated using the smart infeed and feedback modules of Sinamics S120 drives, rendering

costly and loss-prone reactive power compensation units on the end users premises superfluous.

CONTROL CABINETS ALSO HELP EFFICIENCY

Control cabinets, along with the required dissipation of heat, have a significant impact on the

energy balance of a machine. Siemens can supply machine tool builders with a complete control

cabinet that is designed with optimum energy management in mind. Various cooling options exist,

including cold plate and direct fluid cooling, which reduce the need for air-conditioning in the control

cabinet and make waste heat produced by the drive systems available elsewhere in the form of process

heat.

SIZER THE CONFIGURATION TOOL FOR ENERGY-EFFICIENT DRIVES

Sizer is the Siemens software tool used to configure energy-efficient drives. It calculates energy

consumption and losses incurred with the anticipated load cycles (ramp-up, idle running, running under

load, braking, cycle times etc.), as well as the influence of regenerative feedback. This allows the

energy efficiency of alternative motor/converter combinations to be evaluated. Using this information,

configuration of the feed and main spindle axes can be optimized in line with the process and the

anticipated cyclical work flows. Sizer also helps users to avoid over-dimensioning, also in terms of

infeed, and to minimize energy consumption.
