(5) While the alarm code is displayed, press the
key to have the corresponding alarm item
number (e.g.
A
) and data (e.g. Output frequency) displayed alternately in intervals of
approximately 1 second. You can also have the item number (e.g.
A
) and data (e.g. Output
current) for any other item displayed using the
and keys.
(6) Press the

Running status
This shows the running status in hexadecimal. Refer to
" Displaying running status

A
Cumulative run
time
Shows the content of the cumulative power-ON time counter of the
inverter.
Unit: thousands of hours.
(Display range: 0.001 to 9.999, 10.00 to 65.53)
When the total ON-time is less than 10000 hours (display: 0.001 to
9.999), data is shown in units of one hour (0.001). When the total
time is 10000 hours or more (display: 10.00 to 65.53), it is shown in
units of 10 hours (0.01). When the total time exceeds 65535 hours,
the counter will be reset to 0 and the count will start again.
A
No. of startups
Shows the content of the cumulative counter of times the inverter is
started up (i.e., the number of run commands issued).
1.000 indicates 1000 times. When any number from 0.001 to 9.999
is displayed, the counter increases by 0.001 per startup, and when
any number from 10.00 to 65.53 is counted, the counter increases
by 0.01 every 10 startups. When the counted number exceeds
65535, the counter will be reset to 0 and the count will start again.
A
DC link bus

Shows the DC link bus voltage of the inverter main circuit.
Unit: V (volts)
