Setting the Efficiency Equation (η Formula)
Press 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.

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

1 P1 to P4 can be set within the range of the installed elements.
2 PΣA to PΣB can be set within the range of the wiring unit that is automatically determined by the installed
elements.
3 Pm2, Pm3, and Pm4 can be set when AUX modules are installed in slots 3, 5, and 7, respectively.
Setting Delta Computation (Δ Measure)
Press the
Δ
Measure
soft key to display the following screen.
The set wiring systems
Set the delta computation type.
The available options vary depending on
the set wiring systems.
Installed elements
Set the delta computation mode
(rms, mean, dc, r-mean, ac).
