acceleration and deceleration ramp

[Pigreco]

Good morning.
Could someone explain to me how the acceleration or deceleration ramps tread?
My colleagues always use 0.5 m/s^2 dictated by experience.
I didn't find any texts about it.
Thank you.

depends, in general, it is data that provides you with automation, unless you impose a certain curve; or are data that can provide you with an engine supplier for example, if you are talking about engines, in which it tells you that the engine can face a certain transient.

depends if you want to know how to determine and calculate the acceleration and deceleration ramps that are characteristics of the engines with speed variation and are characteristics of the engines themselves and of the type of drive used; This is a complex matter for which there is a wide range of university documentation on the network and on the sites of producers.
if you are interested in value instead, it is defined by the type of application, the cycle of operation, the inertias in play, etc.
try to look at this document (Drive selection and sizing examples) from which I extracted the attached image and see if you clarify your doubts a bit or you better explain what you need with more details.

grazie, per

thank you, I understood that the mechanics of drives is a complex topic, and for one that did not ing. it becomes difficult to understand such matter. I thought there was a simplified way to explain the concept of the ramps of acc. and Dec. and understand the factors that you give to 0.5 m/s^2.
I try to give a peek you have motor manufacturers.. .
Thanks anyway. . .

depends mainly on the dynamics required by the machine.
on the basis of the project data the sizing of the mechanical-servation group is provided.
Obviously that 0.5 m/s^2 is a conservative value that for the machines in question "works".
