Fig. 3−21 Part of the POS function block
Purpose
l The travel profile generator of the POS function block generates a speed travel profile with the
corresponding setpoints for:
− position setpoint (POS−SETPOS),
− speed feedforward control value and (POS−NOUT) and
− torque precontrol value (POS−MOUT).
l The travel profile is generated with regard to the defined travel profile parameters:
− target position (VTPOS),
− traversing speed (VTVEL)
− acceleration (VTACC)
− deceleration (VTACC)
− final speed (VTVEL).
l The travel profile parameters are always read by the profile generator at the beginning of a
positioning process and remain unchanged for the entire positioning time. The override inputs
(POS−V−OVERRID, POS−A−OVERRID) are taken into consideration during this process.
The values given in the variable tables VTxxx can already be changed for the next positioning
while the current positioning is still running.
