Therefore, CSTP_S which represents the synchro-nized stopping status will not change, but it will instead remaining as the during normal oper-ation status.Ending Synchronized StoppingWhen any of the following states occur, CSTP_S (Synchronized Stopping Status) in the SVC-MD_IO field will become “0: During normal operation”, and synchronized stopping will endwith the servo OFF state.• When feedback speed is less than Pn666 (Synchronized Stopping End Speed) (normalend)• When the SV_OFF or DISCONNECT command was received• When the synchronized stopping axis changes to the servo OFF state due to an alarm orfor other reasonsAfter synchronized stopping ends, commands can be received from the host controller.InformationSpeedTimeFeedback speed0Pn666(Synchronized StoppingEnd Speed)0Alarm statusSpeedFeedback speedServo ON/OFF statusTimeOFFONNormal status Alarm statusNormal status Warning statusSynchronizedstopping axisActive alarm axisCSTP_S inSVCMD_IO fieldA.97C(Synchronized StoppingOccurred)Duringsynchronizedstopping*During normal operationTracks the activealarm axis and stops.An alarm occurs.Information
