An alarm that necessitates animmediate stop will prompt the operation A, an immediate stop, if the setting value is 4, 5, 6 or 7. An alarm thatdoes not require an immediate stop will result in the actions specified with the operation B; i.e. either application ofthe dynamic brake (DB) or free-run. (Refer to section 6-5-5.)Hold the main circuit power until deceleration stop is completed.Refer to 7-1 “List of Protective Functions” for alarms that require an immediate st*3 “During deceleration” refers to the section from the state where the motor is operating until the speed is reduced to 30r/min or below. Once the speed reduction achieves 30 r/min and thus it transfers to the “After stop” state, thepost-stop actions will be performed regardless of the motor speed.
