2.15.8 Display of the life of the inverter parts [Pr. 255 to 259]
(common)
Degrees of deterioration of main circuit capacitor, control
circuit capacitor, cooling fan and inrush current limit circuit
can be diagnosed by monitor.
When any part has approached the end of its life, an alarm
can be output by self diagnosis to prevent a fault.
(Use the life check of this function as a guideline since the
life except the main circuit capacitor is calculated
theoretically.)
For the life check of the main circuit capacitor, the alarm
signal (Y90) will not be output if a measuring method of (4)
is not performed.
(1) Life alarm display and signal output (Y90 signal) [Pr. 255]
Whether any of the control circuit capacitor, main
circuit capacitor, cooling fan and inrush current limit
circuit has reached the life alarm output level or not
can be checked by [
Pr. 255 Life alarm status display
]
and life alarm signal (Y90).
The life alarm signal (Y90) turns ON when any of the
control circuit capacitor, main circuit capacitor,
cooling fan and inrush current limit circuit reaches the
life alarm output level.
For the terminal to output Y90 signal, assign 90
(positive logic) or 190 (negative logic) to any of
[
Pr.190 to 196 Output terminal function selection
],
[
Pr.190 to 192 Output terminal function selection
], or
[
Pr.190, 192 Output terminal function selection
].
When using a built-in option (FR-A7AY, FR-A7AR) in
, the following life signals can be
output individually: control circuit capacitor life signal
(Y86), main circuit capacitor life signal (Y87), cooling
fan life signal (Y88), and inrush current limit circuit life
signal (Y89).
