Activate the Lubrication Cycle several times via the HMI - Prepare - Pwr-up Cond. HMI screen. After the lubrication cycles have been completed, it is now necessary to run-in the ballscrew. This can be accomplished by moving the axis back and forth along the entire length of travel at half rapid speed for 30 minutes.

Then allow the ballscrew to cool for 45 minutes.

Once completed, the ballscrew can now be fully loaded.
