11.2 Sensor Module External SME20
11.2.1 Description
Direct encoder systems outside the cabinet can be connected to the Sensor Module External
SME20. The SME20 evaluates these encoder systems and converts the calculated values to
DRIVE-CLiQ.
Incremental direct encoder systems with SIN/COS (1 Vpp) and reference signal can be
connected.
It is possible to connect a motor with a 17-pole circular connector for the encoder to the 12-
pole circular connector of the SME20 using adapter cable 6FX 8002-2CA88-xxxx.
● KTY/PTC temperature sensors can be used for evaluation of the motor temperature.
● The Sensor Module is only suitable for motors without absolute track signals (C/D track):
– Induction motors (e.g. 1PH)
– Synchronous motors with pole position identification (e.g. 1FN, 1FW, 1FE)
Neither motor nor encoder data are saved in the SME20.
11.2.2 Safety Information
CAUTION
Connecting cables to temperature sensors must always be installed with shielding. The
cable shield must be connected to the chassis potential at both ends over a large surface
area. Temperature sensor cables that are routed together with the motor cable must be
twisted in pairs and shielded separately.
