Restrictions
• Acceleration and deceleration curves can include intervals with a
positive slope as well as intervals with a negative slope and also
intervals with 0 slope.
• The slope of the curve intervals can be 1 min
-1
/sec (rpm/sec) minimum
and 1000 min
-1
/sec (rpm/sec) maximum.
• Quadratic curve intervals are only possible between 0 and 1000 min
-1
(rpm) maximum. If a final speed > 1000 min
-1
(rpm) is selected, this
interval will automatically become linear above 1000 min
-1
(rpm).
• The possible runtime results from the maximum possible speed
(depending on the rotor) and from the slope limitation.
Example 1: Start speed 0 min
-1
(rpm), final speed 100 min
-1
(rpm),
runtime 1 hour not possible, since the necessary slope < 0.03 min
-1
(rpm), which means that it is beyond the defined range.
Example 2: Start speed 0 min
-1
(rpm), final speed 15000 min
-1
(rpm),
runtime 10 sec. not possible, since the necessary slope is 1500 min
-1
(rpm), which means that it is beyond the defined range.
