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 and 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. There is
no further conversion of the encoder signal in the drive system.
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
because, for example, the encoder system is identified auto-
matically.
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).
Overview of motor encoder systems
Not every encoder is available for every motor frame size.
