Overview

The "Ctrl-Energy" function provides you with the following options to improve the energy
utilization of your machine.
Ctrl-E Analysis: Measuring and evaluating the energy consumption
Acquiring the actual energy consumption is the first step to achieving better energy
efficiency. The energy consumption is measured and displayed at the controller using the
SENTRON PAC multi-function device.
Depending on the configuration and connection of the SENTRON PAC, you have the
possibility of either measuring the power of the whole machine or only a specific load.
Independent of this, the power is determined directly from the drives and displayed.
Ctrl-E Profiles: Control of energy saving states of the machine
To optimize the energy consumption, you have the option of defining energy saving profiles
and saving them. For instance, your machine has a basic and a more sophisticated energy-
saving mode - or under certain conditions, automatically switches itself off.
These defined energy states are saved as profiles. At the user interface, you have the
possibility of activating these energy-saving profiles (e.g. the so-called tea break key).
NOTICE
Ctrl-E Deactivating profiles
Disable Ctrl-E profiles before a series startup in order to prevent the NCU unintentionally
shutting down.
