Reported event: the 211123 - cpci motion control assembly 3.0 reported the event of "multiple error messages".Method and results: device evaluation and results: per engineering evaluation, it was found that the terminal connection for the 5v rail had a loose screw which allowed for the terminal to intermittently disconnect with vibration.This termination is made by our supplier, (b)(4) on the cpci card cage assembly.Disruption of the 5v rail connection would directly induce a communication failure as the 5v rail connection powers the devices which enable robot motor controller to cpci computer communication.The reported event was confirmed.Device history review: a review of the dhr associated with (b)(4) found qips passed with no notes or comments.-complaint history review: based on the device identification, the (b)(6) complaint databases were reviewed from 2011 to present for similar reported events regarding the cpci motion control assembly 3.0.There have been no other events for the referenced lot number.Conclusions: per engineering evaluation, it was found that the terminal connection for the 5v rail had a loose screw which allowed for the terminal to intermittently disconnect with vibration.This termination is made by our supplier, (b)(4) on the cpci card cage assembly.Disruption of the 5v rail connection would directly induce a communication failure as the 5v rail connection powers the devices which enable robot motor controller to cpci computer communication.The reported event was confirmed.Corrective action/preventive action: (b)(4) was opened to address this issue.
