6.21 ENCODER as drive object
Encoders can be linked in as autonomous drive objects (Drive Object =DO) and evaluated.
An ENCODER drive object can be addressed as encoder via PROFIBUS/PROFINET as an
independent unit.
Using an ENCODER drive object allows an encoder of an upstream machine to be directly
connected via a Sensor Module without having to take an indirect route via the 2nd encoder
of a drive. The encoder is connected via an encoder interface of a Sensor Modules. If the
Sensor Modules, to which the encoder is connected, has its own DRIVE-CLiQ interface (e.g.
an SME20), then the encoder can be connected to any free DRIVE-CLiQ socket via the
Sensor Module.
6.21.1 Preconditions for creating an ENCODER drive object using STARTER
● STARTER V4.1.5 or higher
● Project with one CU320-2
The project can also be created OFFLINE. A description of this can be found in the
SINAMICS S120 Commissioning Manual in Chapter "Commissioning".
Connection conditions for ENCODER drive objects
● All encoders that can be assigned to a drive can be used.
● ENCODER drive objects may be connected to all DRIVE-CLiQ ports.
