5.123 L_SdIntegrate - integration of speed to position
This FB integrates a speed to a position.
• The calculation is made with remainder handling.
• The bLoadStartPos input serves to load the starting position pending at the dnStartPos_p input
into the integrator.

Note!
The FB is not suitable for modulo measuring systems!
(No clocked (Modulo) positions are provided.)
Identifier/data type Information/possible settings
dnSpeedIn_s
DINT
Speed in [rpm]
• 15000 rpm ≡ 2 26 ≡ 67108864
bLoadStartPos
BOOL
Load integrator with starting position and reset overflow signal.
TRUE Load the integrator with the value applied to input dnStartPos_p and
reset bError to FALSE.
dnStartPos_p
DINT
Starting position in [inc] with which the integrator is loaded by setting
bLoadStartPos to TRUE.
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 16
Identifier/data type Value/meaning
dnPosOut_p
DINT
Position in [inc]
• Overflow is possible (display via bError)
bError
BOOL
Status signal "Overflow occurs"
• Status signal can be reset via bLoadStartPos.
TRUE Overflow has occurred.
