Inputs
Identifier/data type Information/possible settings
bEnable
BOOL
Activate FB
FALSE FB deactivated:
• The dnPosOut_p output position and the dnSpeedOut_s output
speed behave according to the deactivation mode set in C05051.
• The bInTarget status signal is reset.
Caution: Depending on the set deactivation mode, sudden changes
may occur at the position and speed output when the FB
(bEnable = TRUEFALSE) is deactivated!
In this case, make sure that no drive motion is derived from these
output signals!
TRUE FB activated:
• The dnPosOut_p output position and the dnSpeedOut_s output
speed display the required position profile according to the profi-
le parameters and control signals set.
bExecute
BOOL
Execute positioning according to the positioning mode set
FALSE Abort of positioning (profile generator inactive):
• When a running positioning mode is aborted, the speed is led to
zero via the stop ramp set in C05056/3.
FALSETRUE Executing the positioning:
• Positioning is executed depending on the set profile parameters
(ramp times, maximum speeds, positioning modes).
• If the positioning mode 1 or 2 is set in C05050, a renewed FAL-
SETRUE edge is required at this control input for the start of
each positioning profile.
bSetPosZero
BOOL
Change over to internal zero position
FALSE The dnSetPos_p input signal is used as position target for the traver-
sing profile.
TRUE Zero is used as position target for the traversing profile.
dnSetPos_p
DINT
Selection of the target position in [increments]:
• Absolute position target (for absolute positioning modes 0 and 1) or traversing
distance (for relative positioning mode 2).
dnActPos_p
DINT
Feedback of the current position in [increments]
• The FB L_LdPosCtrlLin generates positioning profiles on the basis of setpoints on-
ly. Thus, only connect setpoint-based position signals to this input.
• In the simplest case, directly return the dnPosOut_p position output to the
dnActPos_p input.
• Never connect this input to real position signals (e.g. FDB_dnActualPos_p).
AxisData Machine parameters
• If the FB is to relate to the measuring system of the drive axis, connect this input
to the output DI_AxisData of the LS_DriveInterface SB for accepting the machine
parameters of the drive/motor.
• 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)
• For a cam application, this FB can receive the XAxisData/YAxisData X/Y axis data
structure of the L_CamProfiler FB. ( 162)
