  SME20/SME25 Sensor Module External

  SME20/SME25 Sensor Modules External are encoder evaluation units for machine encoders (direct measuring systems).
  The devices are designed with IP67 degree of protection. This means that the units can be installed outside the control cabinet near the machine encoder.

  The following encoder signals can be evaluated:

  • Incremental encoder sin/cos 1 V_pp without rotor position track (C and D tracks)
  • Absolute encoder EnDat 2.1
  • SSI absolute encoder ¹⁾ with incremental signals sin/cos 1 V_pp (firmware V2.4 and later)

  Using adapter cable 6FX8002‑2CA88‑..., it is possible to connect a motor with a 17‑pole circular encoder connector to the 12-pole circular connector of the SME20.

  • KTY/Pt1000/PTC temperature sensors can be used to evaluate the motor temperature (only possible with SME20).
  • The Sensor Module is only suitable for motors without absolute track signals (C and D tracks), e.g.:
    • Synchronous motors with pole position identification (SIMOTICS L‑1FN/T‑1FW/M‑1FE)
    • Asynchronous motors (induction motors) (SIMOTICS M-1PH)

  SME20/SME25 Sensor Modules External evaluate the encoder signals and convert the information obtained to DRIVE-CLiQ. Neither motor nor encoder data are saved in the SME20/SME25.

  ¹⁾ For SME25, only encoders with 5 V supply voltage.

  Дизайн

  SME20/SME25 Sensor Modules External feature the following connenctions and interfaces as standard:

  • 1 encoder connector via circular plug
  • 1 DRIVE‑CLiQ interface with integrated 24 V DC electronics power supply from the Control Unit or Motor Module
  • 1 PE (protective earth) connection

  Интеграция

  SME20/SME25 Sensor Modules External communicate with a Control Unit via DRIVE‑CLiQ.

  ¹⁾ The maximum cable length at the encoder system interface depends on the current drawn by the encoder system and the cross-section of the supply conductors in the cable, however, a maximum of 10 m (32.8 ft) (for detailed information, see Manual SINAMICS S120 Control Units).
