16.30 Safety Spindle Parameters

(PR) #51301 SF_SDisable
Set the spindle to be outside the scope of smart safety observation.
0 : Enable smart safety observation
1 : Disable smart safety observation
(Note) The settings of "#51101 SF_Disable" and "#51301 SF_SDisable" must be the same within a multi-
hybrid drive unit.
(PR) #51302 SF_SStoptype
Select which of the safe stop methods to use when an error is detected in the smart safety observation.
0 : STO
1 : SS1
(PR) #51303- SLS_SSpeed1-4
51306
Specify the upper limits of machine-end speed determined as safe for each of SLS speed tolerances 1 to 4.
If the SLS detection delay time has elapsed with the command/FB speed exceeding the safely-limited speed
while SLS is ON, a safe stop (SS1 or STO) is executed. The safely-limited speed to be applied to SLS is
calculated using the following equation.
Safely-limited speed = SLS speed tolerance x SLS speed override / 100
---Setting range---
0 to 999999.9 (r/min)
(PR) #51307- SLS_SOverride1-16
51322
Specify the speed overrides 1 to 16 with respect to SLS speed tolerances 1 to 4. For details refer to SLS
speed tolerances 1 to 4.
---Setting range---
0 to 100 (%)
(PR) #51323 SLS_Sclamp
Specify the speed clamp ratio that is applied while SLS is ON.
Set the ratio to about 80 to 90%. While SLS is ON, the command speed is clamped at the following speed:
Clamp speed = Safely-limited speed x SLS speed clamp ratio / 100
(Safely-limited speed = SLS speed tolerance x SLS speed override / 100)
---Setting range---
0 to 100 (%)
#51324 SLS_ST1
Specify a period of time to detect a speed error while SLS is ON. A safe stop (SS1 or STO) is executed if the
period of time set in this parameter has elapsed with the command/FB speed exceeding the safely-limited
speed.
---Setting range---
0 to 9999 (ms)
#51325 SLS_ST2
Specify a period of time to detect a deceleration error that is caused due to change of the safely-limited speed
at the start of or during SLS. If you have changed the safely-limited speed at the start of or during SLS, and
the time set in this parameter has elapsed with the command/FB speed exceeding the safely-limited speed,
a safe stop (SS1 or STO) is executed. When set to 0, the detection time is treated as 200(ms).
---Setting range--
0 to 99999 (ms)
