4.2 Parameter Settings Related to Synchronized Stopping4.2.1 Synchronized Stopping Mode Selection4-44.2 Parameter Settings Related to Synchronized Stopping4.2.1 Synchronized Stopping Mode SelectionSynchronized Stopping has three modes, and these modes are set with Pn665 = n.X(Synchronized Stopping Selection).Synchronized Stopping Mode 1If an alarm occurs on either axis A or axis B, position control will be performed on the synchro-nized stopping axis using the feedback position of the active alarm axis as the target position.Synchronized Stopping Mode 2If an alarm occurs on either axis A or axis B, speed control will be performed on the synchro-nized stopping axis using the feedback speed of the active alarm axis as the target speed.Synchronized Stopping Mode 3If an alarm occurs on either axis A or axis B, the synchronized stopping axis is also set to theservo OFF state.Both axes are changed to the servo OFF state almost simultaneously, and both axes arestopped according to the Servomotor stopping method when the servo is turned OFF.4.2.2 Synchronized Stopping End Speed SettingSynchronized stopping will be ended when the feedback speed of the active alarm axis is lessthan Pn666 (Synchronized Stopping End Speed).Use Pn666 (Synchronized Stopping End Speed) to set the speed for judging that the Servomo-tor has stopped and ending synchronized stopping. This parameter is valid for synchronizedstopping mode 1 and 2.Parameter Description When Enabled ClassificationPn665n.0(default set-ting)Disable synchronized stopping.After restart Setupn.1 Enable synchronized stopping mode 1.n.2 Enable synchronized stopping mode 2.n.3 Enable synchronized stopping mode 3.With synchronized stopping mode 1 and 2, the Servomotor may vibrate and the deviationbetween axes may increase when synchronized stopping is performed due to the mechanicalcharacteristics or gain setting.Use this function by first operating the machine or product at low speed and confirming that thedeviation between axes causes no problems.All AxesImportantPn666Synchronized Stopping End SpeedSetting Range Setting Unit Default Setting When Enabled Classification1 to 65,535 1000 referenceunits/s 256 Immediately SetupAll AxesPosition
