General information

Availability of option
This option is available for the following S120 Cabinet Modules:
● Motor Module in chassis format
● Booksize Cabinet Kit
Description
The SMC30 Sensor Module is used for detecting the actual motor speed. The signals
emitted by the rotary pulse encoder are converted here and made available to the 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
