PSA03 **SST SS1/SS2 monitoring deceleration time
Set a deceleration time of the SS1 function and SS2/SOS function. This parameter is used
for the following two functions.
(1) When setting time passes during deceleration of the SS1 function, the STO function will
operate.
(2) When setting time passes during deceleration of the SS2/SOS function, the stop
observation (SOS) will operate. (This function is available with MR-D30 with software
version A1 or later. For MR-J4-_A_-RJ and MR-J4-_B_-RJ, this function is available
with the servo amplifiers with software version B5 or later.)

PSA04 **SSS SS2/SOS standstill speed
Set a standstill speed. When an absolute value of the servo motor speed is lower than the
set value of this parameter, the servo motor will be assumed as stopped.
Concretely, this parameter is used for the following two functions.
(1) When the speed becomes slower than the set value of this parameter during
deceleration of the SS2/SOS function, the stop observation (SOS) will operate.
(2) When the speed becomes higher than the set value of this parameter during stop
observation (SOS) of the SS2/SOS function, the STO function will operate.
This parameter is available with MR-D30 with software version A1 or later. For MR-J4-_A_-
RJ and MR-J4-_B_-RJ, this parameter is available with the servo amplifiers with software
version B5 or later.

PSA05 **SSDP SOS allowance value of position deviation
Specify an allowance value of a position deviation during stop observation (SOS) of the
SS2/SOS function. When the position travels equal to or more than the specified value in
this parameter after the stop observation has started, the STO function will operate.
The SOS allowance value of the position deviation will be clamped at 100 rev when [Pr.
PSA06 SOS allowance value of position deviation unit selection] is set to "0".
This parameter is available with MR-D30 with software version A1 or later. For MR-J4-_A_-
RJ and MR-J4-_B_-RJ, this parameter is available with the servo amplifiers with software
version B5 or later. 3

PSA06 **SAOP1 SOS allowance value of position deviation unit selection
Select a setting unit of the SOS allowance value of the position deviation set in [Pr. PSA05].
This parameter is available with MR-D30 with software version A1 or later. For MR-J4-_A_-RJ and MR-J4-_B_-
RJ, this parameter is available with the servo amplifiers with software version B5 or later.

PSA07 **SLSDT1 SLS deceleration monitoring time 1
Set a threshold of the time from when the SLS1 command is enabled to when the speed
observation starts. Specify enough time for deceleration to a safety speed from the
enabled SLS1 command. As necessary, execute such as deceleration control with the
controller during the delay time.
