data in hourly units. When the total time is 10,000 hours or
more (display: 10.00 to 65.53), the display will change to units
of 10 hours. When the total time exceeds 65,535 hours, the
display returns to 0 and the count will start again.
A
No. of startups The motor run times (the number of times the inverter run
command is set to ON) are calculated and displayed.
1.000 indicates 1,000 times. When any number from 0.001 to
9.999 is displayed, the display increases by 0.001 per startup,
and when any number from 10.00 to 65.53 is displayed, the
display increases by 0.01 every 10 startups.
