Ctrl-E Analysis

In order to sensitize users to the topic of energy efficiency, the power and energy data of the
machine are first acquired.
Acquiring and evaluating energy consumption
A control system with SINUMERIK Operate without a connected measuring instrument
determines the power directly from the drives and displays this.
Additional consumption-relevant data can be retrieved and displayed at the control using the
additional SENTRON PAC Power Monitoring Device.
Depending on where the SENTRON PAC measuring transducer is installed, you have the
possibility of either measuring the power of the whole machine or only a specific load.
With an integrated measuring function, the energy consumption during a measuring period
can be acquired for all drives together with an additional measuring location – and the electrical
power drawn for a selected load can be recorded with respect to time.
Display of energy consumption
● The user can see a graphic of the current power consumption in the first status line of the
"Machine" operating area.
● Additionally, in the Ctrl-Energy initial display the user is shown the consumption in the form
of colored bars, which indicate the current power and the results of today's and yesterday's
long time measurement.
Maximum measuring time
The maximum measuring time for energy between start and stop as well as for an NC part
program is, as a result of the trace recording, 922 seconds (00:15:22).
