■Alarm occurrence
The SS1 function is activated also when an alarm occurs. After an alarm occurs, the servo motor decelerates by either the
dynamic brake, electronic dynamic brake, or forced stop. At the same time, the time from when the SS1 function is activated
is measured, and the STO function is activated when the time set in [Pr. PSA03 SS1/SS2 deceleration monitor time] has
elapsed. For the alarms that activate the SS1 function, refer to "List of alarm No./warning No." in the User's Manual
(Troubleshooting). For how to return to normal operation, refer to the following.
