SMC30 Sensor Module for detecting the actual motor speed (option K50)

4.9.18.1

Description

The SMC30 Sensor Module is used for determining the actual motor speed. The signals
emitted by the rotary pulse encoder are converted here and made available closed-loop
controller via the DRIVE-CLiQ interface for evaluation purposes.
The following encoders can be connected to the SMC30 Sensor Module:
● TTL encoder
● HTL encoder
● SSI encoder
● KTY or PTC temperature sensor

Note
For HTL encoders, in order to reduce the effect of interference, a bipolar connection is
recommended.
