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 ( 283)
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.
