Overview

Built-in encoder systems without
DRIVE-CLiQ interface
For motors without an integrated DRIVE-CLiQ interface, the
analog encoder signal in the drive system is converted into a
digital signal. For these motors as well as external encoders,
the encoder signals must be connected to SINAMICS S120
via Sensor Modules.
Built-in encoder systems with
DRIVE-CLiQ interface
For motors with an integrated DRIVE-CLiQ interface, the analog
encoder signal is internally converted to a digital signal. No
further conversion of the encoder signal in the drive system is
required. The motor-internal encoders are the same encoders
that are used for motors without a DRIVE-CLiQ interface. Motors
with a DRIVE-CLiQ interface simplify commissioning and
diagnostics, for example, as the encoder system is identified
automatically.
The different encoder types, incremental, absolute, or resolver,
are all connected with one type of MOTION-CONNECT
DRIVE-CLiQ cable.
Short designations for the encoder systems
The first letters of the short designation define the encoder type.
This is followed by the resolution in signals per revolution if S/R
is specified (for encoders without DRIVE-CLiQ interface) or in
bits if DQ or DQI is specified (for encoders with DRIVE-CLiQ
interface).
