Parameter
Power saving instantaneous monitor (
On the power saving monitor
during commercial power supply operation (estimated value) is calculated and displays on the
main monitor.
In the following case, the power saving monitor
● Calculated values of the power saving monitor are negative values.
● During the DC injection brake operation.
● Motor is not connected (output current monitor is 0A).
On the power saving rate monitor
displays the power saving rate on the assumption that power (estimated value) during com-
mercial power supply operation is 100%. When Pr. 895 = 1, the power saving rate on the
assumption that the Pr. 893 "Energy saving monitor reference (motor capacity)" value is 100%
is displayed.
Power saving average value monitor (

Power saving average value monitor can be displayed when a value other than "9999" is set in
Pr. 897 "Power saving monitor average time".
The power saving average value monitor
power saving amount at averaging.
The average value is updated every time an average time has elapsed after the Pr. 897 setting
is changed, power is turned on or the inverter is reset, assuming as a starting point. The power
savings average value update timing signal (Y92) is inverted every time the average value is
updated.
