Storage Guidelines
The chemicals in the electrolytic capacitors and other electronic parts of the drive change over time. When you store
the drive for long periods of time, use the information in this section to help keep the performance life estimates.
◆
Storage Location
•
Temperature and Humidity
When you store the drive for approximately one month, for example during shipping, you can put the drive in a
location where the temperature is -20 °C to +70 °C (-4 °F to +158 °F). Correctly package and store the drive during
shipping to prevent vibration and impact damage.
Do not put the drive in direct sunlight or where there will be condensation or ice. Put the drive in a location where
the relative humidity is 95% or less.
•
Dust and Oil Mist
Do not keep the drive locations with dust or oil mist. For example, cement factories and cotton mills.
•
Corrosive Gas
Do not keep the drive in locations with corrosive gas. For example, chemical plants, refineries, and sewage plants.
•
Salt Damage
Do not keep the drive in salty locations. For example, locations near the ocean, and salt damage-designated
locations.
Do not keep the drive in unsatisfactory locations. Keep all drives in storage rooms that are safe from unsatisfactory
elements.
◆
Regular Application of Power
To prevent deterioration of the capacitors, Yaskawa recommends that you apply power to the drive a minimum of one
time each year for a minimum of 30 minutes.
If you store the drive for longer than two years and do not apply power, Yaskawa recommends that you use a variable
power source and gradually increase the power from 0 V to the rated drive voltage over a period of 2 to 3 minutes.
Apply power for a minimum of 1 hour with no load to reform the main circuit electrolytic capacitor. When you
operate the drive after you apply power, wire the drive correctly and check for drive faults, overcurrents, motor
vibration, motor speed differences, and other defects during operation.
