Note
Diminished level of interference immunity due to equalizing currents via the electronics
ground
Ensure that there are no electrical connections between the encoder system housing and the
signal cables, or the encoder system electronics.
If this is not carefully observed, under certain circumstances the system will not be able to reach
the required interference immunity level (there is then a danger of equalization currents
flowing through the electronics ground).
NOTICE
Damage through use of incorrect DRIVE-CLiQ cables
The use of incorrect or unreleased DRIVE-CLiQ cables can cause damage or functional faults to
devices or the system.
• Only use suitable DRIVE-CLiQ cables that have been released by Siemens for the particular
Note
Function equipotential bonding for distributed DRIVE-CLiQ nodes
Integrate all of the components that are connected via DRIVE-CLiQ in the functional
equipotential bonding concept. You make the connection by mounting on bare metallic
machine and plant units that are all connected to one another.
Alternatively, you can establish equipotential bonding with a conductor (min. 6 mm²), which is
routed as far as possible in parallel to the DRIVE-CLiQ cable. This involves all distributed DRIVE-
CLiQ nodes, e.g. DME20, SME20, SME25, SME120, SME125.
Note
Malfunctions due to polluted DRIVE-CLiQ interfaces
Malfunctions can occur in the system through the use of polluted DRIVE-CLiQ interfaces.
• Cover unused DRIVE-CLiQ interfaces with the supplied blanking covers.

Description

The Sensor Module Cabinet-Mounted SMC10 is an expansion module for snapping on to a
standard mounting rail acc. to EN 60715. It evaluates encoder signals and transmits the speed,
actual position value, rotor position and, if necessary, the motor temperature via DRIVE-CLiQ to
the Control Unit.
The SMC10 is used to evaluate sensor signals from resolvers.
