hi,

i want to control a motor using in amusement park.

the application requires ramp up time of 20 to 50 sec and ramp down of 20sec.

which i ve to use? (SS or VFD)

jjj

dear sir,

i would like to give some of notes depeding on your valuable requiest ,

i think that the choice between VFD and Soft starter depending on the application
so if you need to control with variable speed related to the change of voltage and frequency you can use VFD ,
therefor , if you need to control with variable speed related to the change of voltage only you can use Soft starter


i hope to provide with a good engineering knowlage

regards
