Chapter 12 Inverter Function
12.19.14 Outputting a warning based on the
amount of power-on hours
• I want to know when the number of power-on
hours reaches a certain period of time.
• I want to output with a signal the number of
operating hours of the system in which the inverter
has been incorporated.
• Assign the output terminal function 025 [ONT]
power-on time over signal to one of [CC-01] to
[CC-07] that corresponds to the output terminal
and output the signal.
• Assign 025 (ONT) to the output terminal.
• Specify the power-on time level [CE-36].
• The power-on time over signal [ONT] will be
output when the cumulative total of inverter
operating hours exceeds the time specified with
the RUN time/power-on time level [CE-36].
Parameter
• When specifying the time level as a guideline for
replacement, use a number with an adequate
margin.
• Setting example
When you want to generate a warning after the
inverter has been turned on for (300 days 24
hours 3 years =) 21,600 hours, set [CE-36] to
21,600.
Second time onward:
When you want to generate a warning after an
operation of (250 days 8 hours 5 years =)
10,000 hours, set [CE-36] to [dC-24] + 10,000.
