◆ Periodic Maintenance

The drive has Maintenance Monitors that keep track of component wear. This feature provides advance maintenance
warning and eliminates the need to shut down the entire system for unexpected problems. The drive allows the user to
check predicted maintenance periods for the components listed below.
• Cooling Fan, Circulation Fan, Control Board Cooling Fan
• Electrolytic Capacitors
• Inrush Prevention Circuit
• IGBTs
For replacement parts, contact the distributor where the drive was purchased or contact Yaskawa directly.
