Maintenance

The drive Maintenance Monitors keep track of component wear and tell the user when the end of the estimated
performance life is approaching. The Maintenance Monitors prevent the need to shut down the full system for
unexpected problems. Users can set alarm notifications for the maintenance periods for these drive components:
• Cooling fan
• Electrolytic capacitor
• Soft charge bypass relay
• IGBT
Contact Yaskawa or your nearest sales representative for more information about part replacement.

Replaceable Parts
You can replace these parts of the drive:
• Control circuit terminal board
• Cooling fan, circulation fan
• Keypad
Note:
Make sure that you use a keypad with FLASH number 1004 or later. Keypads with FLASH numbers 1003 and earlier will not show
characters correctly.
If there is a failure in the main circuit, replace the drive.
If the drive is in the warranty period, contact Yaskawa or your nearest sales representative before you replace parts.
Yaskawa reserves the right to replace or repair the drive as specified by the Yaskawa warranty policy.
DANGER! Electrical Shock Hazard. Do not examine, connect, or disconnect wiring on an energized bypass. Before servicing,
disconnect all power to the equipment and wait for the time specified on the warning label at a minimum. The internal capacitor
stays charged after the bypass is de-energized. The charge indicator LED extinguishes when the DC bus voltage decreases below
50 Vdc. When all indicators are OFF, remove the covers before measuring for dangerous voltages to make sure that the bypass is
safe. If you do work on the bypass when it is energized, it will cause serious injury or death from electrical shock.

Part Replacement Guidelines
Table 8.7 shows the standard replacement period for replacement parts. When you replace these parts, make sure that
you use Yaskawa replacement parts for the applicable model and design revision number of your drive.
Cooling fan
*1
Electrolytic capacitor
*1 If there is damage to parts that you cannot repair or replace, replace the drive.
Note:
The performance life estimate uses these operating conditions. Yaskawa provides these conditions so you can replace parts to maintain
performance. Unsatisfactory conditions or heavy use will make it necessary for you to replace some parts more frequently than other parts.
Operating conditions for performance life estimate:
• Yearly average
–IP20/Open Type enclosure: 40 °C (104 °F)
–IP20/UL Type 1 and External Heatsink Installation of IP55/UL Type 12: 30 °C (86 °F)
• Load factor
80% maximum
• Operation time
24 hours a day

Monitors that Show the Lifespan of Drive Components
The drive keypad shows percentage values for the replacement parts to help you know when you must replace those
components. Use the monitors in
