l Traversing profile parameters can be changed via input POS−PARAM−RD even during a
positioning process.
Stop!
For the "Manual jog function with intermediate stop", POS−PARAM−RD has to be set = LOW.

l
The profile generator works on an optimum time base using the L profile, i.e. the target
position can be reached as quickly as possible with the acceleration and speed selected.
l The acceleration selected is effective immediately when the velocity is changed.
l Default setting: L profile.
