7.19 PROFIenergy profile for PROFINET

Efficiency optimization, method 1
Figure 7-38
The motor operates in partial load mode between no-load operation and the rated motor
torque. Depending on p1580, in the partial load range, the inverter reduces the flux setpoint
linearly with the torque.
Figure 7-39
The reduced flux in the motor partial load range results in higher efficiency.

7.19 PROFIenergy profile for PROFINET
PROFIenergy is an energy management standard for production plants, based on the
PROFINET communication protocol. The functionality is certified and described in the
PROFIenergy profile of the PNO.
The control transfers the PROFIenergy commands in acyclic operation to the inverter in data
set 80A0 hex.
The inverters support the PROFIenergy profile V1.1 and the function unit class 3.
Parameters r5600 to p5614 are reserved for PROFIenergy functions in the inverter.
An application example for energy savings with PROFIenergy is available in the Internet at:

Reduce the flux setpoint in the partial load range of the motor
Qualitative result of efficiency optimization, method 1
Description
Flux setpoint (factory setting: 100%)
Efficiency optimization (factory setting depends on the inverter)
0% Efficiency optimization is deactivated.
100% In no-load operation, the inverter reduces the flux setpoint to 50% of the
rated motor flux.
