Encoder system connection

Introduction

The encoder system should be connected to SINAMICS S120 via DRIVE-CLiQ.
Motors with DRIVE-CLiQ interfaces (e.g. synchronous motors 1FK7 and 1FT7, and induction
motors 1PH7 and 1PH8) are designed for this purpose. These motors simplify commissioning
and diagnostics because the motor and encoder type are identified automatically.
Motors and external encoders without DRIVE-CLiQ interface
Motors without DRIVE-CLiQ interfaces, as well as external encoders without integrated DRIVE-
CLiQ interface, must be connected via Sensor Modules to enable the encoder and temperature
signals to be evaluated. Sensor Modules Cabinet-Mounted (SMC) are available for installation in
control cabinets and Sensor Modules External (SME) for installation outside control cabinets.
If not otherwise specified, only one encoder system can be connected to each Sensor Module.
Motors and external encoders with DRIVE-CLiQ interface
Motors with DRIVE-CLiQ interfaces can be connected to the associated Motor Module directly via
the MOTION-CONNECT DRIVE-CLiQ cables available. The connection of the MOTION-CONNECT
DRIVE-CLiQ cable at the motor has degree of protection IP67.
The DRIVE-CLiQ interface supplies the motor encoder via the integrated 24 V DC supply and
transfers the motor encoder and temperature signals and the electronic rating plate data, such
as a unique identification number, rated data (voltage, current, torque) directly to the Control
Unit. Different encoder cables are therefore no longer required for the various encoder types,
e.g. resolvers or absolute encoders. Wiring can be effected throughout with a MOTION-
CONNECT DRIVE-CLiQ cable.
DRIVE-CLiQ encoder
A DRIVE-CLiQ encoder is an absolute encoder with integrated DRIVE-CLiQ interface (see
Chapter DRIVE-CLiQ encoder (Page 311)).
