16 Machine Parameters
(PR) #51339 SOS_SPositionP
Specify the upper limit of machine-end travel distance (plus side) determined as a safe operating stop. If the
SOS_P detection delay time has elapsed with the command/FB travel distance in the plus direction exceed-
ing that of this parameter while SOS is ON, a safe stop (SS1 or STO) is executed.
* When this parameter is set to 0, "SOS travel distance error" may occur even though the spindle is at a
standstill.
---Setting range---
0 to 9999 (°)
#51340 SOS_ST3
Specify a period of time to detect a travel distance error while SOS is ON. If the time set in this parameter
has elapsed with the command/FB travel distance exceeding the SOS travel distance tolerance (+/-) while
SOS is ON, a safe stop (SS1 or STO) is executed.
---Setting range---
0 to 9999 (ms)
#51341 SS1_ST1
Specify a period of time to detect a deceleration error while SS1 is ON. If the time set in this parameter has
elapsed with the command/FB speed exceeding the SOS stop speed, STO is activated.
---Setting range---
0 to 99999 (ms)
#51342 SS2_ST1
Specify a period of time to detect a deceleration error while SS2 is ON. If the time set in this parameter has
elapsed with the command/FB speed exceeding the SOS stop speed, STO is activated.
---Setting range---
0 to 99999 (ms)
(PR) #51343 STO_SEXEWT
Specify a period of time to wait from when the drive unit receives an STO request from the NC until when
STO is actually executed. Set this time so that the brake is activated within this period of time. When set to
0, the STO execution standby time is treated as 200ms.
---Setting range---
0 to 20000 (ms)
#51344 SF_PDCHK_ST1
Set the waiting time for starting the position deviation diagnosis at Spindle non-interpolation mode. The di-
agnosis of the position deviation at Spindle non-interpolation mode starts after the commanded speed be-
comes consistent and after the time set by this parameter passes. It stops while the command speed is
changing. When set "0", the Spindle position deviation diagnosis waiting time is 20000ms.
---Setting range---
0 to 30000 (ms)
#51345 SF_PDCHK_STOL
Sets the tolerable value of the position deviation (the difference between the commanded position generated
inside NC and the feedback position received from drive unit) in the position deviation diagnosis. When the
position deviation exceeds the tolerable value, the Safe stop (SS1/STO) will be carried out. When set "0", the
tolerable value is 1080°.
---Setting range---
0 to 32767 (°)
(PR) #51347 SEMG_STO_SWT
[M8]
Specify a length of time it takes to complete deceleration stop when safety external emergency stop is im-
plemented.
When not executing deceleration stop, set the parameter to 0.
When executing deceleration stop, subtract "#51343 STO_SEXEWT" from "#13056 SP056" and set the dif-
ference in the parameter.
---Setting range--
0 to 29900 (ms)
