9.2 Overview of Sensor Modules
Sensor Modules Cabinet-Mounted (SMC)
Sensor Modules Cabinet-Mounted SMC10, SMC20, SMC30 and SMC40 can be ordered and
configured separately. They are used when a motor with a DRIVE-CLiQ interface is not available
or when external encoders in addition to the motor encoder are required. Only one encoder
system may be connected to the Sensor Modules Cabinet-Mounted SMC10, SMC20 and SMC30.
The SMC40 supports two encoder systems. The Sensor Modules Cabinet-Mounted evaluate
these measuring systems and convert the calculated values to DRIVE-CLiQ. Motor or encoder
data are not saved.
Note
The Sensor Module Cabinet-Mounted supplies the power to the encoder; however, the Sensor
Module Cabinet-Mounted must be provided separately with 24 V DC.

Sensor Modules External (SME)
The Sensor Modules External SME20, SME25, SME120, and SME125 are only intended for use
on machines (in North America, in accordance with the NFPA 79 "Electrical Standard for
Industrial Machinery"). It is not permissible to connect DRIVE-CLiQ interfaces to other networks,
e.g. Ethernet, but only to the DRIVE-CLiQ interfaces of the components.
