(1) Energy saving monitor list
The following items are monitored by the power saving monitor (Pr. 52, Pr. 54, Pr. 158 = "50").
(Only 1) Power saving and 3) Power saving average value can be output to Pr. 54 (terminal CA) and Pr. 158
(terminal AM))

*1
For communication (RS-485 communication, communication option), the display increments are 1. For example, 10.00kWh indicates that
communication data is 10.
*2
When using the parameter unit (FR-PU04/FR-PU07), "kW" is displayed.
*3
The setting depends on capacities. (01160 or less/01800 or more)
REMARKS
Since four digits are displayed on the operation panel (FR-DU07), the value is displayed in 0.1 increments when a monitor
value in 0.01 increments exceeds 99.99, then rounded up to 100.0. The maximum display is "9999".
As the operation panel (FR-PU04/FR-PU07) is 5-digit display, it displays in 0.1 increments 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".
