[Pr. PSA02_Functional safety setting (**SMD)]
[Pr. PSA02.1_Position/Speed monitor setting]
0: Do not monitor the position/speed.
1: Monitor the position/speed using a servo motor with functional safety.
2: Monitor the speed without using a servo motor with functional safety.
If this functional safety parameter is set incorrectly, [AL. 537 Parameter setting range error (safety sub-function)] occurs.
[Pr. PSA02.2_Time/Deceleration monitor setting]
0: Perform time monitoring (SS1) and deceleration stop monitoring/stop monitoring (SS2/SOS).
1: Perform deceleration monitoring in addition to time monitoring (SS1) and deceleration stop monitoring/stop monitoring
(SS2/SOS).
If this functional safety parameter is set incorrectly, [AL. 537 Parameter setting range error (safety sub-function)] occurs.
[Pr. PSA02.3_Operation mode selection]
0: Standard control mode
4: Linear servo motor control mode
6: Direct drive motor control mode
If [Pr. PSA02.1 Position/Speed monitor setting] is not set to "0" (do not monitor the position/speed), set this servo parameter to
the same value as [Pr. PA01.1 Operation mode selection]. If this functional safety parameter is set incorrectly, [AL. 537
Parameter setting range error (safety sub-function)] occurs.
[Pr. PSA03_SS1/SS2 deceleration monitor time (**SST)]
Set the deceleration time for the SS1 function and the SS2/SOS function. This functional safety parameter is used by the
following two functions.
• The STO function activates when the time set in this functional safety parameter elapses when decelerating while using the
SS1 function.
• When using the SS2/SOS function, the deceleration stop monitoring shifts to the stop monitoring (SOS) when the time set
in this functional safety parameter elapses while decelerating.
