I received a notification several times on my last flight "Gimbal Pitch Axis Endpoint Reached".  What does this mean and how may I correct it?  The video still came out great.  
Thanks!

Hi there. Thanks for reaching out. Your issue has been escalated for confirmation and we are working to verify the details. We will keep you informed as we make progress. Your understanding is greatly appreciated. Have a nice day.

Hi, BladeZ. To give you an update, we have received recommendations from our engineers, and they are as follows:
1. Calibrate the gimbal.
2. Avoid an angle that reaches the max endpoint.
The DJI Avata gimbal’s controllable range is from 65° to -80° (tilt), and the mechanical range is 75° to -95° (tilt). Given this, if the gimbal’s tilt angle is adjusted to the maximum tilt angle of 65° before takeoff, the aircraft’s attitude change will exceed 65° to provide stability to the gimbal control after takeoff. If the mechanical range of 75° has been exceeded, the gimbal will not move after reaching its endpoint. At this point, the attitude change will continuously exceed the endpoint. The gimbal will, therefore, quickly recenter to avoid damage. Once recentered, it will restore itself to the angle adjusted before takeoff.
Should you have further concerns, please reach back here at DJI Forum. Thank you, and have a nice day.
