General information

Availability of option
This option is available for the following S120 Cabinet Modules:
● Motor Modules
Description
The SMC10 Sensor Module is used for detecting the actual motor speed and the rotor
position angle. The signals emitted by the resolver 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 SMC10 Sensor Module:
● 2-pole resolver
● Resolver, multi-pole
The motor temperature can also be detected using KTY84-130 temperature sensors or PTC
thermistors.

The maximum encoder cable length is 130 m.
The excitation frequency is synchronized to the current-controller clock cycle and lies in the
range between 5 kHz and 10 kHz.
