Emb-175 flight crew experienced a high engine vibration during climbout. A precautionary air return ...

Narrative:

Flight XXXX from ZZZ to ZZZ1; returned to field right after departing ZZZ. Shortly after takeoff; the captain and I noticed high vibration on engine #2 lp as we climbed through 5;000 - 6;000 feet. Initially; the vibration fluctuated between normal range (green) to amber (caution) range. However; after several seconds; it remained in the caution range. We contacted ATC to level out at 6;000 ft and delay vectors while we ran the QRH checklist. Upon completion of the QRH procedure we kept engine #2 vibration in normal range. The captain and I both came upon the decision to return to ZZZ. There were two previous occurrences of engine vibration on engine # 2 in the aml within the last week. We felt it was prudent to return to ZZZ because we did not want to make any more high power demands; i.e. Climb; with the issue at hand. We requested delay vectors to burn off the fuel in order get below max landing weight limitations. ATC vectored us around; and we successfully landed at ZZZ. No emergency was declared. We returned to the field as it [was the] safest decision to do. With two previous documented occurrences of high engine vibration on #2; we did not want to risk another occurrence. By continuing our climb from 6;000 ft to cruising altitude; it puts the engine in a higher power demand with a high probability of another occurrence.
