The Motor trip cause should be identified from your Group Start Program only.
Plesae check any Priority command has been issued for the Motor from the logic.
Generally each object should have Alarm&Event libraries block (Eg:AlarmCond) to generate the alarm/events. Check status value of the alarm/event block of the motor object,if the status is showing negative value (Eg:-25) then you need to recheck the configuration.(Eg:SrcName/CondName/Message,etc...,) For details,please refer online help.
If you are using any specific libraries,then important parmeters of this block are exposed for configuration and suggest you to recheck it.
If you still face the problem,please contact the regional supportline for the assitance.
