Introduction

The sensor system should be connected to SINAMICS S120 via DRIVE-CLiQ.
Motors with DRIVE-CLiQ interfaces (e.g. synchronous motors 1FK7 and 1FT6, and induction
motors 1PH7) are designed for this purpose.
These motors with DRIVE-CLiQ interfaces can be connected to the associated Motor
Module via the available MOTION-CONNECT DRIVE-CLiQ cables. In this way, the motor
sensor and temperature signals as well as the electronic type plate data, such as the unique
identification number, rated data (voltage, current and torque) are transferred directly to the
Control Unit. These motors simplify commissioning and diagnosis because the motor and
sensor type are identified automatically.
Motors without DRIVE-CLiQ interfaces
The sensor and temperature signals from motors without DRIVE-CLiQ interfaces, as well as
external sensors must be connected via Sensor Modules. Sensor Modules Cabinet-Mounted
(IP20) for the direct installation in control cabinets and Sensor Modules External (IP67) for
the installation outside control cabinets are currently available, .
Only one encoder system can be connected to each Sensor Module.
Motors with DRIVE-CLiQ interfaces
The encoder systems can be connected to SINAMICS S120 via DRIVE-CLiQ. Motors with
DRIVE-CLiQ interface are available for this purposes, e.g. 1FK7 synchronous motor.
Motors with DRIVE-CLiQ interfaces can be directly connected to the associated Motor
Module via the available MOTION-CONNECT DRIVE-CLiQ cables. 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, e.g. a unique identification number, rated data (voltage, current, torque) directly to the
Control Unit. This means that for the various encoder types - e.g. resolver or absolute value
encoder - different encoder cables are no longer required; just one MOTION-CONNECT
DRIVE-CLiQ cable can be used for all types.
Further information
Motor sensors and temperature signals should preferably be connected to the associated
Motor Module, while external sensors should be connected to the Control Unit.
