Fig. 7-36 Point-to-point positioning with changeover of velocity
Function
•
PS mode (C1311): Select “Absolute PS” or “Relative PS”.
•
The travel profiles of two subsequent positioning processes are set as in point-to-point
positioning except that one final speed is unequal 0. The final speed is reached when the
target position is reached. Positioning will start at this speed. Positioning will start at this
speed.
Select target position from “VTPOS” (selection under C1312/x)
Select traversing speed from “VTVEL” (selection under C1313/x)
Select acceleration from “VTACC” (selection under C1314/x)
Select deceleration from “VTACC” (selection under C1315/x)
Select final speed from “VTVEL” (selection under C1316/x)
•
Point-to-point positioning is possible with the positioning modes (C1210) “absolute” and
“relative positioning”.
Tip!
If a PS with final speed unequal 0 is not followed by a positioning, for instance because of a jump
to “Program end” or the function “Wait for input”, the fault message P09 (impermissible
programming) will be activated. The drive brakes to standstill.
