The function of the sign for the "Final speed" parameter has been revised. Now, the sign will have the following effects in all positioning modes: If the final speed has a positive sign, the final speed will be effective in the direction of the speed in which the drive traverses in the positioning process. A negative direction counteracts the traversing direction of the positioning process.
What happens? In the case of negative profile speeds, the actual final speed is inverted.
When does this behaviour occur?
The behaviour occurs in relative or absolute positioning processes in negative direction. If a final speed with a positive sign is entered in the profile data, it is expected that the final speed will always be effective in the direction of the profile speed.
Which produts are affected? L_TT1P_TablePositioningBase function block from the L_TT1P_TechnologyModules_LM library (V3.10.0.8 and higher)
Short-term measures:
Always select the final speed with the same sign as the relative target position.
