Creating an 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.

Preconditions for creating an ENCODER drive object using STARTER

Requirements
● As of STARTER V4.1.5
● Project with one CU320-2
The project can also be created OFFLINE. A description of this can be found in Section
"Commissioning" in the SINAMICS S120 Commissioning Manual.
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.
● Up to 4 DRIVE-CLiQ HUBs (DMC20 or DME20) can be used to establish a star-shaped
● The DRIVE-CLiQ HUBs must be directly connected to the Control Unit.

wiring of the ENCODER drive objects. This means that a maximum of 19 possible
ENCODER drive objects can be connected to one Control Unit.
(This means that the number of possible ENCODER drive objects is restricted so that a
maximum of 24 drive objects can be connected to one Control Unit.)
