Energy saving operation and energy saving monitor
The following table shows the items which can be monitored by the cumulative saving power
monitor (Pr. 52 = 51). (The monitor value of the cumulative monitor can be shifted to the right with
Pr. 891 "Cumulative power monitor digit shifted times".)

Tab. 6-100:Cumulative saving power monitor list
For communication (RS-485 communication, communication option), the display increments
are "1". For example, the communication data is "10" for "10.00kWh".
When using the parameter unit (FR-PU04 or FR-PU07), "kW" is displayed.
The setting depends on capacities. (01800 or less/02160 or more)
NOTES As the operation panel (FR-DU07) is 4-digit display, it displays in "0.1" increments since a
carry occurs, e.g. "100.0", when a monitor value in "0.01" increments exceeds "99.99". The
maximum display is "9999".
As the operation panel (FR-PU04 or FR-PU07) is 5-digit display, it displays in "0.1" incre-
ments since a carry occurs, e.g. "1000.0", when a monitor value in "0.01" increments
exceeds "999.99". The maximum display is "99999".
The upper limit of communication (RS-485 communication, communication option) is
"65535" when Pr. 898 "Power saving cumulative monitor clear" = 9999. The upper limit of
"0.01" increments monitor is "655.35" and that of "0.1" increments monitor is "6553.5".
