2.4 System block "LS_DigitalFrequencyInput"
The system block LS_DigitalFrequencyInput displays the optional digital frequency
extension module in the FB editor of the »Engineer«.
 The system block must be called cyclically since only then speed and position will be
calculated accurately to increments.

Position setting
Position setting ( 12)
FALSEÊTRUE Sets the 32-bit absolute position output at the output
DFIN_dnActualPos_p to the value which is applied to input
DFIN_dnReferencePos_p.
DFIN_dnReferencePos_p
DINT
Absolute position in [increments], to which the output DFIN_dnActualPos_p is set by
a FALSE-TRUE edge at input DFIN_bLoadReferencePos.

Machine parameters
• To transfer the machine parameters of the drive/motor, connect this input to the
output DI_AxisData of SB LS_DriveInterface.
• The machine parameters of a higher-level drive can be transferred via the
FB L_SdSetAxisData. For this purpose, you have to connect the FB's AxisData
output to this input.
• If the input remains unused, the system block continues to operate as before. In
this case the units are scaled to revolutions.
