4 Maintenance
30 YASKAWA TOEPC71061779B GA800 Drive Installation Manual
Examine and maintain the drive and peripheral devices regularly to extend the life of the drive and decrease
performance deterioration, decrease early wear, and decrease drive failures.
Regular examinations and maintenance will also decrease system downtime.
Refer to the Technical Reference (SIEPC71061737) for more information about maintenance and examinations.
Examine the drive one time each year at a minimum.
The operating conditions, environmental conditions, and use conditions will have an effect on the examination
frequency for connected equipment.
Examine the drive more frequently if you use the drive in bad conditions or in these conditions:
• High ambient temperatures
• Frequent starting and stopping
• Changes in the AC power supply or load
• Too much vibration or shock loading
• Dust, metal dust, salt, sulfuric acid, or chlorine atmospheres
• Unsatisfactory storage conditions.
The drive has Maintenance Monitors that keep track of component wear and warn maintenance period when the
estimated performance life is approaching. This Maintenance Monitor eliminates the need to shut down the entire
system for unexpected problems.
Users can set alarm notifications to inform the maintenance periods for a specific drive component.
