6-10-7 Accumulated Operating Time (n087, n088)
• The accumulated operating time function is provided for 5.5- and 7.5-kW Inverters only.
• This function calculates and stores in memory the Inverter’s accumulated operating time. The accu-
mulated operating time that is saved can be checked (unit: 10h) by the “accumulated operating time”
(U-13) of the multi-function monitor (MNTR indicator).
• Use this function in determining the maintenance schedule.

• Set the initial value for the accumulated operating time with 10 hours set as 1. The accumulation will
begin from the time that is set.
Note To clear (i.e., set to 0) the monitor value (U-13) for the accumulated operating time, set n088 to 0.
The monitor value cannot be cleared by setting n001 (parameter write-prohibit selection/parame-
ter initialization) to 8 or 9 (initialize).
