6.1 Internal interfaces | "LS_Feedback" system block
The LS_Feedback system block provides the internal interfaces for the basic function "Encoder
evaluation" in the function block editor.

Information/possible settings
FDB_dnPosOffset_p
DINT
Offset for position setpoint and actual position in [increments]
FDB_dnActPosIn_p
DINT
External actual position in [increments]
For the selection of an external actual position with a corresponding position
control.
Use of an external position encoder
( 239)

Value/meaning
FDB_dnActualPos_p
DINT
Current position of the position encoder in [increments]
FDB_dnActualSpeed_s
DINT
Current speed of the position encoder in [rpm]
FDB_dnPosFollowingError_p
DINT
Current following error in [increments]
FDB_dnSetPos_p
DINT
Set position calculated by active basic drive function in [increments]
Considering the motor mounting position.
In the case of an active speed or torque control (instead of position control) the
actual position (FDB_dnActualPos_p) is shown at this output.
FDB_dnSetSpeed_s
DINT
Setpoint speed calculated by active basic drive function in [rpm]
Considering the motor mounting position.
FDB_bResolverError
C02579/1 | BOOL
Status signal "Resolver error"
TRUE A resolver error (e.g. open circuit) has occurred.
FDB_bSinCosSignalError
C02579/2 | BOOL
Status signal "sine/cosine encoder error"
TRUE A sine/cosine encoder error has occurred.
