Long Term Storage

Description

This section describes general guidelines for long-term storage of robots and spare parts.

This applies for all robot generations and spare parts.

 

A robot is considered long-term stored when it is stored for a period of 6 months or more.

 
Guidelines

In order to keep the robot and spare parts in its best possible condition, it is recommended to follow normal good practice which is:

  • Storage temperature: 10°C - 30°C

  • Humidity: RH 20-60%

  • Universal Robots recommends to unpack and start up robots at least yearly and let them run a light load program rotating in all joints at least 90 degrees 5 times in each direction to distribute the lubricants.
    If possible, also mount spare parts joints on an arm and perform the same operation routine.

  • In rare occurrences there may be a need for wiping down the robots after storage to remove any excess lubricants that have migrated out of the sealings.

  • The battery is designed to last for the lifetime of the robot and will not be charged when power is applied to the system. The battery service life is 8 to 10 years, but for e-Series and UR Series it can be replaced.

  • Flash memory can lose their data capacity over time, therefore there is a potential risk that the data on e.g. the SD-card will have to re-flashed.
