(PR) #51326- SSM_SSpeed1-4
51329
Specify the upper limits of machine-end speed determined as safe for each of SSM speeds 1 to 4. If the com-
mand/FB speed is at the safe speed or lower while SSM is ON, the Under SSM safe speed signal turns ON.
If the command/FB speed exceeds the safe speed, the Under SSM safe speed signal turns OFF. The safe
speed to be applied to SSM is calculated using the following equation.
(When the Under SSM safe speed signal is ON)
Safe speed = SSM speed
(When the Under SSM safe speed signal is OFF)
Safe speed = SSM speed - SSM hysteresis width
---Setting range---
0 to 999999.9 (r/min)
#51330- SSM_SHysteresis1-4
51333
Specify the hysteresis widths that correspond to SSM speeds 1 to 4. For details refer to SSM speeds 1 to 4.
---Setting range---
0 to 999999.9 (r/min)
(PR) #51334 SOS_SSpeed
Specify the upper limit of machine-end speed determined as a safe operating stop.
If the SOS_V detection delay time has elapsed with the command/FB speed exceeding that of this pa-
rameter while SOS is ON, a safe stop (SS1 or STO) is executed.
The point of time at which the command/FB speed drops to that of this parameter or lower while SS1/
SS2 is ON is treated as a standstill.
*When this parameter is set to 0, "SOS speed error" may occur even though the spindle is at a standstill.
---Setting range---
0 to 9999.9 (r/min)
#51335 SOS_ST1
Specify a period of time to detect a speed error while SOS is ON. If the period of time set in this parameter
has elapsed with the command/FB speed exceeding the SOS stop speed while SOS is ON, a safe stop (SS1
or STO) is executed.
---Setting range---
0 to 9999 (ms)
(PR) #51336 SOS_SDroop
Specify the upper limit of machine-end position deviation determined as a safe operating stop. If the SOS_PD
detection delay time has elapsed with the position deviation (difference between the command and FB posi-
tions) exceeding that of this parameter while SOS is ON, a safe stop (SS1 or STO) is executed.
* When this parameter is set to 0, "SOS position deviation error" may occur even though the spindle is at a
standstill.
---Setting range---
0 to 9999 (°)
#51337 SOS_ST2
Specify a period of time to detect a position deviation error while SOS is ON. If the time set in this parameter
has elapsed with the position deviation (difference between the command and FB positions) exceeding the
SOS position deviation tolerance while SOS is ON, a safe stop (SS1 or STO) is executed.
---Setting range---
0 to 9999 (ms)
(PR) #51338 SOS_SPositionM
Specify the upper limit of machine-end travel distance (minus side) determined as a safe operating stop. If
the SOS_P detection delay time has elapsed with the command/FB travel distance in the minus direction ex-
ceeding 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 stand-
still.
---Setting range---
0 to 9999 (°)
