5.124 L_SdIntegrateAxis - speed to position integration (with TP correction)
This FB integrates a speed to a position.
• In contrast to the FB L_SdIntegrate , in the case of this FB a correction of the position output via
touch probe can additionally be effected, i. e. the integrator considers the time from the detec-
tion of a touch probe to the next task cycle.
• The bLoadStartPos input serves to load the starting position pending at the dnStartPos_p input
into the integrator.
• A touch-probe-exact (mark-controlled) start of the integrator can be carried out.
• In addition to the position, the resulting speed is shown at the output dnSpeedOut_s.
• The FB can be used for all measuring systems (modulo/limited/unlimited).
Inputs

Identifier/data type Information/possible settings
dnSpeedIn_s
DINT
Speed in [rpm]
• 15000 rpm ≡ 2 26 ≡ 67108864
• Display parameter: C04352
bLoadStartPos
BOOL
Load integrator with starting position and reset error output.
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.
• C04353 indicates the starting position in the real unit of the machine.
dnTpPos_p
DINT
Position of the touch probe sensor in [increments].
• C04354 indicates the position in the real unit of the machine.
dnTpTimeLag
DINT
Input for accepting the touch probe time stamp
• Connect this input with the output dnTouchProbeTimeLag of the corresponding
touch probe system block.
