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.

Inputs

Identifier

Data type

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)

FDB_

bResetPosFollowingError

BOOL

Input for deleting the following error
True

The position setpoint is equated with the actual position value.

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.

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.
