Since the SS1 function is also used for emergency stop when an internal diagnostic error is detected, refer to the following to set the functional safety parameters.
Page 360 ■Alarm occurrence The SS1 function is activated also when an alarm occurs.

Page 361 Deceleration monitoring function When the SS1 command is input, this function starts deceleration and monitors whether the servo motor decelerates according to the deceleration time constant. If the deceleration set by the functional safety parameter cannot be performed, the STO function is executed. The STO function is activated even when the time specified by [Pr.

Sequence outline The SS2/SOS function is activated by turning off SS2C (SS2 command).
Page 367 Deceleration stop monitoring ■Speed monitoring during deceleration During deceleration, when both the absolute value of the speed command and the absolute value of the speed feedback become equal to or less than the value set in [Pr. PSA04 Safety sub-function - Stop speed], deceleration is considered to have been completed, and stop monitoring (SOS) starts.
Page 368 ■Deceleration monitoring When [Pr. PSA02.2 Time/Deceleration monitor setting] is set to "1", speed monitoring can be performed. After the SS2 command is turned off and the time set in [Pr.
