4.4 Sensor Module Cabinet 20 (SMC20)
4.4.1

Description

The 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
Control Unit.
The connectable encoders are incremental encoders SIN/COS (1 Vpp) and absolute
encoders EnDat.
The maximum signal cable length is 100 m.
The module may be snapped on to a DIN50022 mounting rail.
