(5) Cumulative energization time and actual operation time monitor (Pr. 171, Pr. 563, Pr. 564)
Cumulative energization time monitor (Pr. 52 = "20") accumulates energization time from shipment of the inverter every
one hour.
On the actual operation time monitor (Pr. 52 = "23"), the inverter running time is added up every hour. (Time is not added
up during a stop.)
If the monitored value exceeds 65535, it is added up from 0. You can check the numbers of cumulative energization time
monitor exceeded 65535h with Pr. 563 and the numbers of actual operation time monitor exceeded 65535h with Pr. 564.
Writing "0" to Pr. 171 clears the cumulative energization power monitor. (The cumulative time monitor can not be cleared.)
REMARKS
The actual operation time is not added up unless the inverter is operated one or more hours continuously.
If "0" is written to Pr. 171 and Pr. 171 is read again, "9999" is always displayed. Setting "9999" does not clear the actual operation
time meter.
(6) You can select the decimal digits of the monitor (Pr. 268)
As the operation panel display is 4 digits long, the decimal places may vary at analog input, etc. The decimal places can
be hidden by selecting the decimal digits.
In such a case, the decimal digits can be selected by Pr. 268.
Pr. 268 Setting
9999 (initial value) No function
For the first or second decimal places (0.1 increments or 0.01 increments) of the monitor, numbers in the first
0 decimal place and smaller are rounded to display an integral value (1 increments).The monitor value smaller than
0.99 is displayed as 0.
When 2 decimal places (0.01 increments) are monitored, the 0.01 decimal place is dropped and the monitor
1
displays the first decimal place (0.1 increments). The monitored digits in 1 increments are displayed as they are.
REMARKS
The number of display digits on the cumulative energization time (Pr. 52 = "20") and actual operation time (Pr. 52 = "23") does
not change.
