The invention discloses a drop suppression method and device, a servo driver and a servo control system, and the method comprises the steps: increasing the gain of a target control loop in response to an enable signal or a band-type brake release signal of a target part; and controlling a target motor to drive a target component to move based on the increased target control loop gain so as to perform gravity drop suppression on the target component when the target component is released based on the enable signal or the band-type brake release signal, and reducing the target control loop gain when the gravity drop suppression is completed so as to restore the target control loop gain to the original gain. The falling suppression method is easy to implement, position falling of the component under the action of gravity can be reduced, and the nodding phenomenon is avoided or weakened. 本发明公开了一种跌落抑制方法和装置、伺服驱动器、伺服控制系统，所述方法包括：响应于目标部件的使能信号或抱闸释放信号，增大目标控制环增益；基于增大后的目标控制环增益控制目标电机带动目标部件运动，以在基于使能信号或抱闸释放信号释放目标部件时，对目标部件进行重力
