Sensor Module Cabinet-Mounted SMC10

7.3.1

Description

The Sensor Module Cabinet-Mounted 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 rms 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 the ohmic resistance R and the inductance L (the primary winding of the
resolver) determines whether the resolver can be evaluated with the SMC10. See the
