5.1.4.1 Curves
With the “curve function” user defined accelerations and decelerations can be
created. Curve numbers 20 – 29 are available. The intervals no. 1 – 10 of each
curve consist of fix points which are defined by time and speed. In the event that
the speed of one interval is higher than the set speed for the run, the curve speed
can be limited or allowed or starting can be prohibited.
CUT ⇒
Speed in one interval is automatically limited to the set speed for
the run.
ADMIT ⇒
Chosen speed in one interval is allowed.
CANCEL ⇒
A stop occurs. Starting is not possible without to a change of the
curve speed in one interval.
For interval no. 1 a linear (LIN) or quadratic (QUAD) acceleration can be chosen.
All further accelerations are linear.
Furthermore, run profiles can be created. The following conditions must be
fulfilled:
- The max. preset final speed of one interval corresponds to the set speed of
the run.
- The total time corresponds to the set time of the run.
- The final speed of the last interval is 0.
