5.11.3.5 The PROFIdrive profile
User data structure in the PROFIdrive profile
PROFIdrive as an inverter interface on PROFIBUS or PROFINET
The SINAMICS G120 inverters are controlled via the PROFIdrive profile, version 4.1. The
PROFIdrive profile defines the user data structure with which a central control communicates
with the inverter by means of cyclic or acyclic data transfer. The PROFIdrive profile is a
cross-vendor standard.
Cyclic communication
Description
The PROFIdrive profile defines different telegram types. Telegrams contain the data
packages for cyclic communication with a defined meaning and sequence. SINAMICS G120
inverters have the telegram types listed in the following table.
