Setting the Efficiency Equation (ηFormula)
Press
WIRING
and then the
η Formula
soft key to display the following screen.
The set wiring systems
Set the denominator and numerator of
the efficiency equation to the active
power and motor power measurement
functions.
(P1 to P6,

You can set up to four equations: η1 to η4.
Installed input elements
To add active powers and motor output and use them in η1 to η4, use Udef1 and Udef2.
Define Udef1 and Udef2

1 Can be set within the range of the installed input elements.
2 Can be set within the range of the wiring unit that is automatically determined by the installed input
elements.
3 Can be set on models with the /MTR option.
