5.94 L_LdPosCtrlLin - Master value adjustment via position
This FB permits the time-controlled profile generation with linear acceleration/deceleration ramps.
The following positioning functions, for instance, can be implemented via this FB:
• Online trimming of offset positions on the master and drive end
• Positioning of the drive to the position of the electrical shaft
• Position override function: Separate the drive from the curve position and put it in a safe posi-
tion
Function library: LenzeLineDrive

 Note!
The FB always operates in the absolute measuring system independent of the setting in
the AxisData machine parameters. Thus, the dnPosOut_p position output is not limited
to a cycle length in case of a Modulo system.
Only the position value at the dnPosOut_p position output should be used in the appli-
cation.
The dnSpeedOut_s speed output must not be integrated because the integrated position
cannot be displayed completely using the dnPosOut_p output for internal technical re-
asons!
