Sensor Modules
Sensor Modules are needed when additional temperature sensors are to be connected via
DRIVE-CLiQ. Various Sensor Modules are available to do this:
●
Sensor Module Cabinet-Mounted (SMC) for rail mounting in control cabinets
●
Sensor Module External (SME) in degree of protection IP67, installed close to the motor
PTC, KTY84, PT1000 temperature sensors - and in some cases - bimetallic NC contacts,
can be connected to the Sensor Modules.

Sensor Module Cabinet-Mounted
A Sensor Module Cabinet-Mounted (SMCx0) evaluates the sensor signals. The results are
transferred to the drive for further processing via DRIVE-CLiQ. The SMCx0 is intended for
operation in a control cabinet. SMC10, SMC20, SMC30 and SMC40 differ regarding the
encoder interfaces. They have the same function for detecting the motor temperature.
Alternatively, an SMC30 offers two encoder connections. The encoder can either be
connected at interface X520, a 15 pin Sub-D connector – or at interface X521/X531, via
terminal strip.
A SMC40 only supports pure digital encoders without incremental signals. These are only
encoders with the order designation EnDat 22. In contrast to the other Sensor Modules, the
SMC40 is a double SMC. Wiring is via two DRIVE-CLiQ cables. Motor temperature
monitoring is not possible with the SMC40.
Note
The SMC40 can only be fully configured when an associated EnDat 2.2 encoder is
connected. Without a connected encoder, it is not possible to integrate the SMC40 into the
topology.
Note
No safety functions with SMC40
No safety functions are supported with firmware V4.5.
