Energy saving monitor list
The following table provides the items that can be monitored by the power saving monitor
(Pr. 52 = Pr. 54 = Pr. 158 = 50). (Only
can be output to Pr. 54 (terminal CA) and Pr. 158 (terminal AM)).

FR-A700 EC
Description and Formula
Difference between the estimated value of
power necessary for commercial power supply
operation and the input power calculated by the
inverter
Power during commercial power supply opera-
tion − input power monitor
Ratio of power saving on the assumption that
power during commercial power supply opera-
tion is 100%
