14.40.5 Accumulated Power Consumption History

According to the parameters "#1371 PwrIntegIntvl (Power consumption accumulation interval)" and "#1392 StartTimeIPC
(Power consumption accumulation start time)", the control records the accumulated power consumption (1) and (2) as shown
in the figure below and the time stamp (Accumulation start time) in a file so that the accumulation data can be obtained as an
accumulated consumption history file. Among the values, a plus means power consumption, while a minus means power
regeneration.
The signals "Power consumption computation: Enable consumption accumulation 1 to 4 (IPCE1 to 4: Y724 to 7)" are not used
for creating the accumulated power consumption history.

 How to start creating accumulated power consumption history
 Set the "#1371 PwrIntegIntvl (Power consumption accumulation interval)" in the range of 0 to 999 [hr]. Also set the "#1392
StartTimeIPC (Power consumption accumulation start time)" in the range of 0 to 23 [o'clock]. It is not possible to specify the
date with this parameter.
 Turn the power OFF and ON again. If you have changed the parameter setting in (1), the accumulated power consumption
history is cleared, and new consumption accumulation is started. If you set the "#1371 PwrIntegIntvl (Power consumption
accumulation interval)" to 0 [hr], however, the accumulation will not start.
