  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.

  • SIMOTICS M-1PH8 and SIMOTICS S-1FT7/1FK7 synchronous motors
  • SIMOTICS M-1PH8 asynchronous motors (induction motors)
  • SIMOTICS T-1FW3 torque motors

  Motors with a DRIVE-CLiQ interface can be directly connected to the associated Motor Module using MOTION-CONNECT DRIVE-CLiQ cables. The MOTION-CONNECT DRIVE-CLiQ cable connection 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 with varying permissible lengths, can be used for all encoders.

  These motors 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.

  Дальнейшая информация

  Motor encoder and temperature signals must be connected when possible to the corresponding Motor Module or Power Module and external encoders to the Control Unit. However, the DRIVE-CLiQ connections can also be bundled via DRIVE-CLiQ Hub Modules.

  Safety Integrated

  The Safety Integrated Extended Functions of the SINAMICS S120 drive system require suitable encoders (see section SIMOTICS servomotors).

  Motors driving a load via a belt

  Unfavorable material combinations generate static electricity between the belt pulley and the belt. Electrostatic charging must be prevented, since this can discharge via the motor shaft and the encoder, thereby causing disturbances in the encoder signals. One countermeasure is to manufacture belts out of an antistatic material, for example.
