Encoder connection on motors without DRIVE-CLiQ
If a motor is not equipped with a DRIVE-CLiQ interface, the speed encoder and temperature
sensor are connected via a signal connector.
Motors that are not equipped with DRIVE-CLiQ require a Sensor Module Cabinet-Mounted
(SMC) or a Sensor Module External (SME) when operated with SINAMICS S120. The motor is
connected to the SMC or the SME via the signal cable. The SMC or SME is connected to the
Motor Module via a MOTION-CONNECT DRIVE-CLiQ cable.

Cables on motors without DRIVE-CLiQ
Prefabricated cables from Siemens (MOTION-CONNECT) must be used. These oer many
advantages over self-assembled cables in terms of operational reliability, quality and availability.
For technical data and length code, see Catalog, Chapter "MOTION-CONNECT connection
system".
Maximum assignment of signal terminal strips in the terminal box
The following signals can be connected to the signal terminal strip:
• Temperature sensor (+1R1; -1R2): For an additional reserve temperature sensor, +1R1 and
-1R2 are connected to the signal terminal strip and (for motors with encoder) also wired to
the signal connector.
• Reserve-temperature sensor (+2R1, -2R2):
– Shaft height 80-160: Option A25
– Shaft height 180-280: Standard
• Additional PTC thermistor circuit for alarm and trip (1TP1, 1TP2, 2TP1, 2TP2): Option A12
