Sensor Module Cabinet-Mounted SMC20
10.1.1
Description
The Sensor Module Cabinet-Mounted SMC20 evaluates encoder signals and transmits the
speed, actual position value, rotor position and, if necessary, the motor temperature and
reference point via DRIVE-CLiQ to the S120 Combi.
The SMC20 is used to evaluate encoder signals from incremental encoders with SIN/COS (1
Vpp) or absolute encoders with EnDat 2.1 or SSI.

Product-specific safety instructions
WARNING
Danger to life if the fundamental safety instructions and remaining risks are not carefully
observed
If the fundamental safety instructions and remaining risks in Chapter 1 (Page 21) are not
observed, accidents involving severe injuries or death may occur.
• Adhere to the fundamental safety instructions.
• When assessing the risk, take into account residual risks.
WARNING
Fire hazard due to overheating because of inadequate ventilation clearances
Inadequate ventilation clearances can cause overheating with a risk for personnel due to
smoke and fire. This can also result in increased failure rates and a shorter service life for
Sensor Modules.
• Maintaining 50 mm ventilation clearances above and below the component is essential.
NOTICE
Damage when connecting an impermissible number of encoder systems
If more than the maximum permissible number of encoder systems are connected to a
Sensor Module, this will cause damage.
• At a Sensor Module only connect the maximum permissible number of encoder
systems.
