Main Circuit Capacitor/Cooling Fan Replacement Timing
■
When to replace the main circuit capacitor and cooling fan
The converter counts cumulative operation time in one hour.
You can check cumulative operation time by using the monitor item: tin0. At the same time, the remaining life
of the main circuit capacitor and that of the cooling fan are displayed in the monitor items (timer remaining
time 1: tin1 and timer remaining time 2: tin2) as a guide.
For details of monitor items, refer to {4.2.4. Checking Operating State} and {4.2.5. List of Monitor Items}.
When a value of the timer remaining time 1: tin1 becomes less than
or equal to "0," this indicates that it is time to replace the
main circuit capacitor and that replacement of the capacitor is
recommended.
When a value of the timer remaining time 2: tin2 becomes less than
or equal to "0," this indicates that it is time to replace the
cooling fan and that replacement of the fan is recommended.
For replacing the main circuit capacitor, refer to {7.4. Inspecting and Replacing Main Circuit Capacitor}. For
replacing the cooling fan, refer to {7.3. How to Replace Cooling Fan}.
■
Default setting of the cumulative operation timer
You can change a setting of cumulative operation time with the cumulative operation timer (1): F-02 and the
cumulative operation timer (2): F-03. In the initial state, they are set as follows:
･
Cumulative operation timer (1): F-02: Guide of remaining life of the main circuit capacitor
･
Cumulative operation timer (2): F-03: Guide of remaining life of the cooling fan
Each amount of time indicates a guide of remaining life, and it does not assure their behaviors.
For details of F-02 and F-03, refer to {5.3.7. Area F}.
