The invention provides a holder parameter adjusting method, a device and holder equipment. The method comprise steps that, when a holder parameter adjusting event is detected, power supply for a motor is controlled, and rotation angle speed data at each time point of a holder shaft controlled by the motor is recorded; angular acceleration data at each time point can be acquired through calculation according to the rotation angle speed data at each time point, frequency conversion for the angular acceleration data is carried out, and peak value frequency in a preset frequency range is determined; the peak value frequency is configured to be trap wave frequency of the motor so as to filter signals which are in the trap wave frequency and are to be sent to the motor. Through the method, in a use process of a holder hanging a new load, attitude control on the hung load can be realized relatively stably, the realization mode is simple and convenient, no user participates in the configuration process, user time is saved, manpower cost is reduced, and automation and intelligentization demands of the user are satisfied.
