Chapter 12 Inverter Function
12.19.13 Outputting a warning based on the
number of operating hours
• I want to know when the number of operating
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 024 [RNT]
RUN time over signal to one of [CC-01] to [CC-07]
that corresponds to the output terminal and output
the signal.
• Specify the RUN time/power-on time level [CE-36].
• The RUN time over signal [RNT] 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
First time:
When you want to generate a warning after an
operation of (250 days 8 hours 5 years =)
10,000 hours, set [CE-36] to 10,000.
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-22] + 10,000.
