Motors with DRIVE‑CLiQ interface

DRIVE‑CLiQ is the preferred method for connecting the encoder systems to SINAMICS S120.

Motors with DRIVE‑CLiQ interface are available for this purpose, e.g.

• 1PH8/1FT7/1FK7 synchronous motors
• 1PH8 asynchronous motors (induction motors)
• 1FW3 torque motors

Motors with a DRIVE‑CLiQ interface 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 and rated data (voltage, current, torque) to the Control Unit. This means that for the various encoder types - e.g. resolver or absolute encoder - different encoder cables with varying permissible lengths are no longer required; just one cable type, MOTION‑CONNECT DRIVE‑CLiQ, can be used for all encoders.

Motors with DRIVE‑CliQ interface simplify commissioning and diagnostics, as the motor and encoder type are identified automatically.

Motors without DRIVE‑CLiQ interface

The encoder and temperature signals of motors without DRIVE‑CLiQ interface, as well as those of external encoders, must be connected via Sensor Modules. Sensor Modules Cabinet-Mounted are available in degree of protection IP20 for control cabinet installation, as well as Sensor Modules External-Mounted (degree of protection IP67).

Only one encoder system can be connected to each Sensor Module.
