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 Vpp (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/PTC temperature sensors can be used for motor temperature evaluation (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 (1FN, 1FW)
  • Asynchronous motors (induction motors) (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.
