Cumulative run time
Shows the cumulative power-ON time of the inverter.
Unit: thousands of hours.
When the total ON-time is less than 10000 hours (display: 0.001
to 9.999), data is shown in units of one hour. When the total time
is 10000 hours or more (display: 10.00 to 65.53), it is shown in
units of 10 hours. When the total time exceeds 65535 hours, the
display will be reset to "0" and the count will start again.
6_08
No. of startups
The cumulative total number of times an inverter run command
has been issued is calculated and displayed.
1.000 indicates 1000 times. When any number ranging 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.
When the total number exceeds 65535, the counter will be reset
to "0" and start over again.
6_09
DC link bus voltage
Shows the DC link bus voltage of the inverter's main circuit.
Unit: V (volts)
