5-9-1 Life Diagnostic Monitor
5-9 Life Monitor
The life diagnostic monitor displays the following conditions:
• The lives of capacitors on the main circuit board
• The cooling fan life
As for signals, a capacitor life prewarning signal (029 [WAC]) and a fan life advance notice signal (030
[WAF]) can be output.
Precautions for Correct Use
• The lives of capacitors are calculated once a ten minutes. If the power supply is repeatedly
turned ON and OFF faster than this cycle, the inverter will be incapable of diagnosing the
lives of capacitors normally.
• If the selection of the cooling fan operation is set to other than 00, the fan will stop automati-
cally depending on the condition. The life diagnosis isn’t carried out while the fan is in the
automatic stop mode.
Parameter
For operation of cooling fan, see 8-5 Cooling Fan Control on page 8-122.
5-9-1 Life Diagnostic Monitor
Item Parameter Data Description
Life diagnostic moni-
tor
[dC-16] LL to HH
The monitors shows H at the end of the life
spans.
The monitor on the right indicates the lives of
the capacitors on the circuit board, whereas
that on the left indicates the life of the cooling
fan.
Capacitor life
advance notice
[CC-01] to [CC-07] 029
[WAC]: This signal is output when the lives of
the capacitors on the circuit board are neared.
Fan life advance
notice
[CC-01] to [CC-07] 030
[WAF]: This signal is output when the cooling
fan rotation speed is decreased.
Cooling FAN control
method selection
[bA-70]
00 Always ON
01
The fan is turned ON during operation and
continues rotating after the operation is
stopped.
02
Running depending on the temperature. The
fan runs as the fin temperature rises.
