Section 11-3
Acceleration Ramp Type [337]
Sets the type of all the acceleration ramps in a parameter set. See Fig. 71.
Depending on the acceleration and deceleration requirements for the applica-
tion, the shape of both the ramps can be selected. For applications where
speed changes need to be started and stopped smoothly, such as a conveyor
belt with materials that can drop following a quick speed change, the ramp
shape can be adapted to a S-shape and prevent speed change shocks. For
applications that are not critical in this, the speed change can be fully linear
over the complete range.
Note
For S-curve ramps the ramp times, [331] and [332], defines the maximum
acceleration and deceleration rated, i.e. linear part of S-curve, just as for the
linear ramps. The S-curves are implemented so that for a speed step below
sync speed the ramps are fully S-shaped while for larger steps the middle part
will be linear. Therefore will a S-curve ramp from 0 –sync speed take 2 x Time
while a step from 0–2 x sync speed will take 3 x Time (middle part 0.5 sync
speed – 1.5 sync speed linear). Also valid for menu [337], D.eceleration ramp
type.
