But adjust thefrequency according to the magnitude ofthe load specifications (moment of inertia,torque).When output frequency ≥ Pr.263Decelerate from the speed obtainedfrom output frequency minus Pr.262.When output frequency < Pr.263Decelerate from output frequencyDecelerate from the speed obtained fromoutput frequency minus Pr.262.Set a deceleration slope down to thefrequency set in Pr.266.◦ ◦ ◦◦ ◦ ◦◦ ◦ ◦◦ ◦ ◦Set a deceleration slope below thefrequency set in Pr.266. ◦ ◦ ◦9999 Same slope as in Pr.264Set the frequency at which thedeceleration slope is switched from thePr.264 setting to the Pr.265 setting.ParametercopyParameterclearAllparameterclear◦: enabled× : disabled◦ ◦ ◦Parameter list85
