16 Machine Parameters
(PR) #51181 SOS_PositionP
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 axis is at a standstill.
---Setting range---
0 to 9999.999 (mm or °)
#51182 SOS_T3
Specify a period of time to detect a travel distance error while SOS is ON. If the period of 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)
#51183 SS1_T1
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)
#51184 SS2_T1
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) #51185 STO_EXEWT
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)
(PR) #51186 SBTEX_Enable
0 : Disable
1 : Enable
(PR) #51187 SBTMO_Enable
0 : Disable
1 : Enable
#51191 SBT_ILIM
Set the current limit value in the brake test in proportion to the stall current. When set "0", the alarm occurs
at the start of the brake test. (The test does not start.)
---Setting range---
0 to 100 (%)
(PR) #51192 SBT_CMDWT
Set the wait time of output of movement command for brake test from NC since receiving SBT starting signal
(SBTSTEXm / SBTSTMOm). When set "0", the commanded wait time is 400ms.
---Setting range---
0 to 30000 (ms)
(PR) #51193 SBT_FD
Set the movement amount to command to the test target axis at the time of brake test. When set "0", the
alarm occurs at the start of the brake test. (The test does not start.)
---Setting range---
-99999.999 to 99999.999 (mm or °)
