Sensor Module Cabinet 20 (SMC20)

4.4.1

Description

The cabinet-mounted sensor module 20 (SMC20) evaluates sensor signals and transmits
the speed/position, 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.
