How much energy saving and cost saving for change of DOL to VSD?

[Derrick_User]

Hi, 

I am just curious how much will I be saving if I change DOL to VSD? 

What is the ROI? How much energy and cost saving will I get?

Thank you.

Hi @Derrick_User derrick,

Hope you are fine.

Let´s see if someone else would answer your question as what I have to share with you are the links for a blog posting from Schneider-UK and an online tool related to our ALTIVAR VSD family that does not compare with DOL but it gives an idea of efficiency of our VSD as required by IEC standard:

Hello @Derrick_User , 

there is one tool from Schneider where you can evaluate the savings and compare DOL and VSD:

Your feedback is welcome, 

Have a nice day,

Hello Delcho,

How can this software tool help on automation sizing of VSD?

If I choose machine, the motor application does not have any conveyor system?

Based on this article, can I say that implementing VSD help to save cost and boost the energy efficiency for my machine?

Thank you.
