The factory setting of the unit of measure is 0.1 s; the ramp time is 10 sec.
Figure 4: Example of S ramps.
You can also select the rounding off and the rounding off percentage for the 4 stages of starting ramp up and the
starting ramp down, and for the end ramp up and the end ramp down (S ramps). The ramp rounding off allows
reaching the reference end value with a zero tangent, both while accelerating and while decelerating, thus suppressing
torque peaks that could damage mechanical couplings.
The rounding off is expressed as a percentage of the ramp time it relates to; if used, it allows increasing the preset
ramp time by half the sum value of the two rounding off values. Its effect is shown in the figures below.
Example:
P009
= 10sec ;
P021
= 1111 binary (rounding off selected for all four ramps);
P022
= 50%;
P023
= 50%
The resulting ramp up time is as follows:
P009
+ ((
P009
* (
P022
+
P023
)/2 )/100 ) = 10 + (( 10* (50+50)/2 )/100 ) = 15 sec
The effect of this rounding off can be seen in the figures below:
