Ctrl-E Profiles

To optimize the energy consumption, you have the option of defining energy saving profiles
and saving them.
Controlling the energy-saving states of the machine
The following pre-defined energy-saving profiles are available when the system is delivered:
● Simple energy-saving mode (machine standby)
A specific interface signal is initiated if the control has not exited the reset state after a
defined time. Using this signal, with the PLC a pre-defined energy state is established,
where, for example it is still possible to operate the machine for setting-up purposes.
● Full energy-saving mode (NC standby)
A specific interface signal is initiated if none of the keys on the machine control panel at
the control has been pressed for a specific time. A pre-defined energy state can be
established with the PLC using this signal, where it is still possible, for example, to transfer
programs to the control or edit them.
● Maximum energy-saving mode (auto shut-off)
An additional interface signal is initiated if, at the control, no key on the operator panel and
machine control panel has been pressed for a defined time and there is no active
communication with the external device. Via the PLC, the main switch is automatically
opened, e.g. using the undervoltage release function.
These predefined energy-saving profiles only become effective if the control system is in the
reset state. They can be blocked using a PLC user signal. The energy-saving profiles can be
changed at any time and supplemented to include up to a total of 8 profiles.
For instance, you have the option of assigning a customer key to an energy-saving profile,
with which the control can be immediately shut down.

Overview

In every machine tool, the PLC is the central part of the control for the peripherals and mounted
equipment/devices. Each machine can have several operating stations.
The energy-saving profiles are managed and stored in the PLC. The signals to monitor energy
within the machine are available in the PLC; these signals can then be appropriately logically
combined in the PLC user program.
