The photoelectric equipment servo system will generate feedback energy due to deceleration braking and generate pump lift voltage, which will cause power supply overvoltage protection. Traditional energy dissipation methods are difficult to effectively solve. This paper studies and analyzes the pump lift voltage problem caused by feedback energy from two aspects: the software and hardware of the servo system. The mechanism of feedback energy action of the servo system is discussed, and several effective methods to deal with the feedback energy are put forward. The pump lift voltage problem from the aspects of servo power supply, servo drive circuit, control parameters are solved. A new zero feeding control method is proposed, with a pump lift voltage suppression rate of 74.7%. Based on a full-bridge drive circuit, the rapid braking of the motor is realized by using the feedback energy, and the pump lift voltage is eliminated at the same time. The debugging and test of the photoelectric equipment servo system has practical engineering guiding significance.
