5.89 L_LdIntegrateCyclic - cyclic integration
This FB integrates a speed in a position (by analogy with the FB L_SdIntegrate) in consideration of
the cycle.
• It is possible to add a position offset to the output position, e.g. for trimming purposes. This
function corresponds exactly to the FB L_LdAddOffsetCyclic
. ( 308)
• The cycle and shift factor for the position resolution are read out of the machine parameters
(AxisData).
• The clock pulse is created with remainder processing.
• The FB is the counterpart of the FB L_LdDifferentiateCyclic
. ( 318)

≡ 67108864
bLoadStartPos
BOOL
Load the integrator with starting position
TRUE Load the integrator with the value at the dnStartPos_p input.
dnStartPos_p
DINT
Starting position in [inc] with which the integrator is loaded by setting
bLoadStartPos to TRUE.
dnPosOffset_p
DINT
Position offset in [inc]
AxisData Machine parameters
• For accepting the machine parameters of the drive/motor, connect this input
with the output DI_AxisData of the SB LS_DriveInterface.
• The machine parameters of a master drive can be displayed with the
FB L_SdSetAxisData
. In this case, the FB output AxisData must be connected to
this input. ( 510)
• If this input is released, the following scaling applies:
1 motor revolution ≡ 2
