№SR-ZSV00039 － 56 －Motor Business Unit, Appliances Company, Panasonic Corporation6－4－4 Emergency Stop at AlarmIf an alarm occurs that requires an immediate stop, setting the following parameters will control the motor toimmediately stop it.(1) Related parametersCategory No. Parameter Setup range Unit Function5 10 Sequence at alarm 07 To set up the states during the deceleration and after the stop whenan alarm occurs.The immediate stop is valid when the parameter is set to either 4, 5,6 or 7.5 11 Torque setup foremergency stop 0500 % To set a torque limit for the immediate stop.5 13 Overspeed level 020000 r/minIf the motor speed exceeds the value set with this parameter, Err26.0“Over-speed protection” occurs.If the value is set to 0, the overspeed level will be set at themaximum number of motor revolution multiplied by 1.2.6 14 Emergency stop time atalarm 01000 msTo set the allowable time for the immediate stop to complete whenthere is an alarm. The time exceeding the value set for thisparameter will force a state of alarm.If 0 is set for this parameter, the immediate stop doesn’t do, andbecome an alarm state immediately.6 15 2nd over-speed levelsetup 020000 r/minIf the motor speed exceeds the value set for this parameter during animmediate stop which has been caused by an alarm, Err26.1 “2ndover-speed protection” will occur.If the value is set to 0, the overspeed level will be set at themaximum number of motor revolution multiplied by 1.2.(2) Item Immediate stop operation when an alarm requiring an immediate stop occurs(Note) To protect against runaway upon instantaneous stopping, specify an allowable excessive speed level inPr6.15 “2nd over-speed level setup”. If 2nd excessive speed protection, which is an error not applicable toinstantaneous stopping, is activated, it immediately leads to error tripping. However, if set lower thanPr5.13 “Over-speed level setup”, a fast shutdown will not be executed due to Err26.1 “2nd over-speedprotection” that occurs before Err26.0 “Over-speed protection”.If Err26.0 and Err26.1 are detected at the same time, Err26.0 will be displayed but a fast shutdown willnot be executed due to Err26.1 that is internally occurring.Torque limitSpeed[r/mn]TimeAlarm state (operation after stop： DB/free-run)Immediate stopoperationNormal operation(per commands from the controller)Motor speedPr5.11For normal operationFor normal operationAlarm requiring immediate stop has occuredNo alarm has occuredAlarmSpeed crite-ria to stop(30r/minIf the time specified by Pr6.14 “Emergency stop time at alarm” has passed since analarm requiring an immediate stop had occurred and if the actual speed is over 30r/min, then an alarm state will be prompted immediately. An alarm not applicableto instantaneous stopping in the drive during a fast shutdown immediately leads toalarm state.Immediate stop time**Pr5.11 “Torque setup for emergency stop” to alleviate shock causedby immediate stop
