Safe Acceleration Monitor (Sam) - Siemens SINUMERIK Series Function Manual

3.9.9

Safe Acceleration Monitor (SAM)

The "Safe Acceleration Monitor" (SAM) function is responsible for safety monitoring braking
along the OFF ramp. This function is active for SS1, SS2 or STOP B and STOP C.
Precondition
The commissioning mode (Page 49) must be activated so that the parameters of this safety
function can be changed. The SAM safety function is only available for the selected drive if,
in options (Page 64), an extended function has been previously set and parameterized.
Settings
In this window, for the drive you can define the limit values for the following options:
Figure 3-16
● Speed tolerance (p9548)
Sets the speed tolerance for the "SAM" function in mm/min for linear axes or rpm for rotary
axes.
● Shutdown speed acceleration monitoring (p9568)
Sets the speed limit for the "SAM" function in mm/min for linear axes or rpm for rotary axes.
Recommended values
If an NC axis is assigned to the drive, then these limit values can also be preassigned using
a dialog. Using softkey "Calculate SAM tol." you can access this dialog with the calculated
recommended values. The actual value from the drive parameters is juxtaposed in the "Value"
