 Number of history data
The data with accumulation values can be obtained up to 48 pieces. If the number of pieces to record exceeds 48, the latest
data is always recorded. At this time, you can include the data without accumulation values in the middle of the history data.
However, if two or more data without accumulation values come in a row, only the top data (the data with the oldest time
stamp) is displayed. The maximum number of history data is 96.
If you record the data with accumulation value and data without accumulation value alternatively, it reaches the maximum
value.
The top data (the data with the oldest time stamp) of the history file is always the data with accumulation value.
 Display of history data
History data is displayed in a chronologically ascending order of the time stamp (Accumulation start time).
If up to the Nth history data have been recorded, the (N+1)th and subsequent data are not displayed. (N = 1 to 95)

14.40.6 Precautions

(1) When you clear each of Accumulated power consumption 1 to 4, and if you turn ON and then OFF the "Power consump-
tion computation: Clearing consumption accumulation 1 to 4 (IPCC1 to 4: Y700 to 3)" without checking the ON status of
the "Power consumption computation: Clearing consumption accumulation 1 to 4 complete (IPCCC1 to 4: X708 to B)",
Accumulated power consumption 1 to 4 may not be cleared.
(2) If a spindle has the spindle/C axis control, the power consumed during C axis control is not calculated as the servo axis
power consumption, but as the spindle power consumption.
(3) Set "#13228 SP228 SFNC8/bit0 to 2" (Load display selection) to "011" (Load display High-cycle).
If you enter "000" (Normal), the power consumption is not properly calculated.
(4) If you turn OFF and ON the power with "#1371 PwrIntegIntvl (Power consumption accumulation interval)" set to "0", Accu-
mulated power consumption is cleared.
