Hello,

I am confused with the values entered here in the torque column in Per unit as the input type is in per unit.

my question is how to get equivalent values from PU to NM ? I mean how to convert from PU to Nm.

How these values in Per unit considered or assumed?

is there any formulas for it?

Also it is the same case for the Loss-speed duty cycle definition.

Hi Sriganeshkumar Ravikumar,

Go to help>Manual and in serch for "Duty Cycle Definition"

You will find the details regarding the per unit values, how to calculate the actual values for both Torque-Speed & Loss-Speed  in this section.

Thanks for the reply

Yes I have seen the Motor CAD help. 

For example in the above image in the torque column you can see the values entered in as PU 1,2.5,.....

But my question is how the PU values are  derived or assumed or considered?

is there any formulas to calculate them?
