Energy saving operation and energy saving monitor
(1) Energy saving monitor list
⋅ The following provides the items that can be 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, the communication data is
"10" for "10.00kWh".
*2 When using the parameter unit (FR-PU04), "kW" is displayed.
*3 The setting depends on capacities. (01160 or less/01800 or more)
REMARKS
⋅ 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) 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".
