Aircraft
Shortly after setting the takeoff power with the auto throttles the airplane veered hard to the left due to the auto throttles commanding the left engine to reduce thrust to well below commanded EPR setting. Takeoff rejected at approximately 50-60 knots and all checklists and procedures accomplished per SOP. Returned to Gate in ZZZ; notified hub maintenance; Dispatch; Maintenance Control and left a voice mail with the Chief Pilot outlining the events which caused the rejected takeoff and subsequent gate return.
Captain reported auto throttle system reduced thrust below commanded on the left engine resulting in a rejected take off and a return to the gate.
