General information

Availability of option
This option is available for the following S120 Cabinet Modules:
● Booksize Cabinet Kits
● Motor Modules in chassis format
Description
The SMC30 Sensor Module is used for determining the actual motor speed. The signals
coming from 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 or bimetallic switch with NC contact
