5. PARAMETERS
No. Symbol
PSA10 **SLSDT4 SLS deceleration monitoring time 4
Set a threshold of the time from when the SLS4 command is enabled to when the speed
observation strats. Specify enough time for deceleration to a safety speed from the
enabled SLS4 command. As necessary, execute such as deceleration control with the
controller during the delay time.
PSA11 **SLSS1 SLS speed 1
Set a threshold of a safety speed for when the SLS function operates by the SLS1
command. When an absolute value of the servo motor speed exceeds this value during the
speed observation of the SLS function, the STO function will operate.
PSA12 **SLSS2 SLS speed 2
Set a threshold of a safety speed for when the SLS function operates by the SLS2
command. When an absolute value of the servo motor speed exceeds this value during the
speed observation of the SLS function, the STO function will operate.
PSA13 **SLSS3 SLS speed 3
Set a threshold of a safety speed for when the SLS function operates by the SLS3
command. When an absolute value of the servo motor speed exceeds this value during the
speed observation of the SLS function, the STO function will operate.
PSA14 **SLSS4 SLS speed 4
Set a threshold of a safety speed for when the SLS function operates by the SLS4
command. When an absolute value of the servo motor speed exceeds this value during the
speed observation of the SLS function, the STO function will operate.
PSA15 **SLST SLS/SS2/SOS speed detection delay time
Specify filtering time of the delay filter which determines whether a servo motor speed is
over or below the threshold during the speed observation. This parameter setting affects
the response time of the next speed observation.
Time after the speed exceeds during the speed observation of the SLS function until the
STO function starts
Time after the speed decelerates lower than the standstill speed during the speed
observation of the SS2/SOS function until the stop observation (SOS) starts (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.)
Time after the speed accelerates higher than standstill speed during the stop
observation (SOS) of the SS2/SOS function until the STO function starts (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.)
PSA17 **SOSPT SOS position detection delay time
Set a filtering time of the delay filter which determines that motor position exceeds the
threshold at position observation. This parameter setting affects the response time of the
next position observation.
Time after the position deviation of position feedback becomes out of the allowance
value of the position deviation during the stop observation of the SS2/SOS function until
the STO function starts
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.
PSA18 **SSMS SSM speed
Set a threshold of a safety speed for when the SSM function operates. SSMS (SSM output)
will turn off when an absolute value of the servo motor speed exceeds this speed and will
turn on when the value is below this speed. However, these determinations include
hysteresis specified with [Pr. PSA19].
When an alarm which disables SSM occurs, SSMS (SSM output) will turn off.
Incorrect setting of this parameter will trigger [AL. 7A.3]. Refer to section 7.2 for details.
PSA19 **SSMHW SSM hysteresis width
Set the threshold of the hysteresis width to be used for the speed judgment of the SSM
function. Be sure to specify a value lower than [Pr. PSA18]. Setting a value of [Pr. PSA18]
or more will trigger [AL. 7A.3 Parameter combination error (safety observation function)].
Refer to section 7.2 for details.
