*1 Position deviations/external scale deviations at the time when an alarm occurs will be retained while the alarm is still
there, and they will be cleared when the alarm is cleared.
*2 The selection of the operation A or B shows whether an immediate stop is executed. An alarm that necessitates an
immediate stop will prompt the operation A, an immediate stop, if the setting value is 4, 5, 6 or 7. An alarm that
does not require an immediate stop will result in the actions specified with the operation B; i.e. either application of
the 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 30
r/min or below. Once the speed reduction achieves 30 r/min and thus it transfers to the "After stop" state, the
post-stop actions will be performed regardless of the motor speed.
