(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 FM) and [ Pr.
158 ] (terminal AM)).
The following items are monitored by the power saving 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 ] .

*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 increments vary according to the inverter capacity. (55K or less/75K or more)
*4 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.
*5 Since five digits are displayed on the parameter unit (FR-PU04/FR-PU07), the value is displayed in 0.1 increments when a
monitor value in 0.01 increments exceeds 999.99, then rounded up to 1000.0. The maximum display is 99999.
*6 When [ Pr. 898 Power saving cumulative monitor clear = 9999], the maximum value of communication (RS-485 communication, communication
option) is 65535. The upper limit of 0.01 increments monitor is 655.35 and that of 0.1 increments monitor is 6553.5.
