Sensor Module Cabinet 30 (SMC30)

4.5.1

Description

The SMC30 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.
TTL (to RS422 standard) and HTL rectangular signal sensors can be connected.
