Description

The Sensor Module Cabinet-Mounted 10 (SMC10) evaluates encoder signals and transmits
the speed, actual position value, rotor position and, if necessary, the motor temperature via
DRIVE-CLiQ to the Control Unit.
The SMC10 can be operated from firmware 2.2 and higher
The SMC10 is used to evaluate sensor signals from resolvers.

The excitation voltage is 4.1 V and cannot be parameterized.
The excitation frequency is synchronized to the current controller clock cycle and lies in the
range between 5 kHz and 10 kHz.
The ratio between ohmic resistance R and inductance L determines whether the resolver
can be evaluated with the SMC10. See the following diagram:

The maximum sensor cable length is 130 m.
The component is snapped on to a mounting rail according to DIN 50022.
