The system block LS_DigitalFrequencyOutput displays the digital frequency output of the
optional extension module in the FB editor of the »Engineer«:
Inputs
Input
Data type
Info/possible settings
DFOUT_dnSpeedSet_s
DINT
Speed in [rpm], which is to be output via the digital frequency output as encoder
signals with TTL level.
• To select this signal source, C13050 / C14050 = "7" must be set.
 Signal source selection ( 23)
DFOUT_bLoadReferencePos
BOOL
Position setting
 Position setting ( 25)
FALSEÊTRUE Sets the 32-bit absolute position output at the output
DFOUT_dnActualPos_p to the value which is applied to input
DFOUT_dnReferencePos_p.
DFOUT_dnReferencePos_p
DINT
Absolute position in [increments], to which the output DFOUT_dnActualPos_p is set
by a FALSE-TRUE edge at input DFOUT_bLoadReferencePos.
 Position setting ( 25)
DFOUT_AxisData
V3.0 or higher
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.
