PROFIenergy - properties of the drive system
SINAMICS drive system devices meet the following requirements:
● The devices are certified for PROFIenergy.
● The devices support PROFIenergy function unit, Class 3.
● The devices support PROFIenergy energy-saving mode 2.
PROFIenergy commands
Principle of operation
At the start and end of pauses, the plant operator activates or deactivates the pause function
of the plant after which the IO controller sends the PROFIenergy "START_Pause" /
"END_Pause" command to the PROFINET devices. The device then interprets the content of
the PROFIenergy command and switches off or on again.
Further PROFIenergy functions can be used to fetch device information during the pauses.
The user can use them to transfer the "START_Pause" / "END_Pause" command in time.
PROFIenergy control commands
START_Pause Switches from the operating state to the energy-saving mode
depending on the pause duration.
Switches from the energy-saving mode to the operating state
depending on the pause duration.
START_Pause_with_time_response Switches from the operating state to the energy-saving mode
and also specifies the transition times in the command re-
END_Pause Switches from the energy-saving mode to the operating state.
Cancels a switch from the operating state to the energy-saving
PROFIenergy query commands

Shows the implemented PROFIenergy profile.
Get_Measurement_List This command returns the measured value IDs that can be
accessed using the "Get_Measurement_Values" command.
