Description

The Sensor Module Cabinet-Mounted SMC40 is an expansion module for snapping on to a
standard mounting rail acc. to EN 60715. It is used to convert encoder signals from absolute
encoders with EnDat 2.2, order designation EnDat22, to DRIVE-CLiQ and transmit them to the
Control Unit. Two encoder systems with EnDat 2.2 order designation EnDat22 can be connected
to the SMC40, which are converted to two DRIVE-CLiQ encoder signals independently of each
other.
Note
Permissible encoders
• Only use absolute encoders EnDat 2.2 with order designation EnDat22. Do not connect an
absolute encoder EnDat 2.2 with the order designation EnDat02.
• Only use absolute encoders (not incremental encoders) with software versions 4.5 and 4.6.
• Do not use any battery-buffered encoders, such as e.g. Heidenhain EBI 1135.
Configuration and commissioning
To make sure that the Sensor Module Cabinet-Mounted SMC40 is integrated into the topology
during first commissioning, observe the following connection conditions:
• Connect at least one of the DRIVE-CLiQ interfaces X500/1 or X500/2 on the SMC40 using
DRIVE-CLiQ.
• Connect one EnDat encoder to the corresponding encoder interface X520/1 (to X500/1) or
X520/2 (to X500/2).
• Operate the SMC40 only in a star topology. The DRIVE-CLiQ sockets X500/1 and X500/2
can not be used for a series connection.
Note
The SMC40 will only be subsequently integrated into the actual topology if the DRIVE-CLiQ
interfaces X500/. and the corresponding encoder interfaces X520/. are assigned. Without a
connected encoder, it is not possible to subsequently integrate the SMC40 into the topology.
Temperature signals
If the EnDat2.2 encoder already evaluates the temperature, the temperature signals can be
transferred through the SMC40 via DRIVE-CLiQ.
