Ctrl-E Profiles
4
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.
4.1 Commissioning the PLC for Ctrl-E Profiles
4.1.1 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.
