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 drive. 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 drive 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 drive is safe. If
you do work on the drive when it is energized, it will cause serious injury or death from electrical shock. The drive has internal
capacitors that stay charged after you de-energize the drive.
