The efficiency of the adjustable frequency drive is defined
as the ratio between the power output and the power
input.

References:
Analog Reference
A signal transmitted to the analog inputs 53 or 54, can be
voltage or current.
Binary Reference
A signal transmitted to the serial communication port.
Preset Reference
A defined preset reference to be set from -100% to +100%
of the reference range. Selection of eight preset references
via the digital terminals.
Ref
Determines the relationship between the reference input
at 100% full scale value (typically 10 V, 20 mA) and the
resulting reference. The maximum reference value set in
3-03 Maximum Reference.
Ref
Determines the relationship between the reference input
at 0% value (typically 0 V, 0 mA, 4 mA) and the resulting
reference. The minimum reference value set in
3-02 Minimum Reference.
