Contents Description
5_00
Cumulative run
time
Shows the cumulative power-ON time of the inverter.
Unit: 1,000 hours.
When the total ON-time is less than 10,000 hours (display: 0.001 to
9.999), data is shown in units of one hour.
When the total time is 10,000 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.
5_01
DC link bus
voltage
Shows the DC link bus voltage of the inverter.
Unit: V (volts)
5_03
Max. temperature
of heat sink
Shows the maximum temperature of the heat sink for every hour.
Unit: ºC
5_04
Max. effective
current
Shows the maximum effective current for every hour.
Unit: A (amperes)
5_05
Capacitance of
the DC link bus
capacitor
Shows the current capacitance of the DC link bus capacitor, based on
the capacitance when shipping as 100%. Refer to Chapter 7
"MAINTENANCE AND INSPECTION" for details.
Unit: %
5_06
Cumulative run
time of electrolytic
capacitors on the
printed circuit
boards
Shows the cumulative time during which a voltage is applied to the
electrolytic capacitors on the printed circuit boards.
Unit: 1,000 hours (Display range: 0.01 to 99.99)
When the count is less than 99,990 hours (Display: 0.01 to 99.99), it is
possible to check data in units of 10 hours (0.01).
When the count exceeds 99,990 hours, it stops and the LED monitor
sticks to 99.99.
5_07
Cumulative run
time of the
cooling fan
Shows the cumulative run time of the cooling fan.
If the cooling fan ON/OFF control (function code H06) is enabled, the
time when the fan is stopped is not counted.
Unit: 1,000 hours (Display range: 0.01 to 99.99)
When the count is less than 99,990 hours (Display: 0.01 to 99.99), it is
possible to check data in units of 10 hours (0.01).
When the count exceeds 99,990 hours, it stops and the LED monitor
sticks to 99.99.
5_08
Number of
startups
Shows the cumulative count of times the inverter is started up (i.e., the
number of run commands issued).
1.000 indicates 1,000 times. When any number ranging from 0.001 to
9.999 is displayed, the count increases by 0.001 per startup, and
when any number from 10.00 to 65.53 is displayed, the count in-
creases by 0.01 every 10 startups.
If the count exceeds 65,535, it will be reset to "0" and start over again.
5_09
Input watt-hour
Shows the input watt-hour of the inverter.
Unit: 100 kWh (Display range: 0.001 to 9999)
Depending on the value of input watt-hour, the decimal point on the
LED monitor shifts to show it within the LED monitors’ resolution
(Display resolution: 0.001
→
0.01
→
0.1
→
1).
To reset the integrated input watt-hour and its data, set function code
E51 to "0.000."
When the count exceeds 1,000,000 kWh, it will be reset to "0."
