Calculating SAM tolerance of the actual speed
● The following rules are valid for the parameterization of the SAM tolerance:
● SAM tolerance
● Recommendation:
Responses
Speed limit violated (SAM):
● STOP A
● Safety message C01706/C30706
System errors:
● STOP F with subsequent STOP A
● Safety message C01711/C30711
Features
● Element of the SS1 (time and acceleration controlled) and SS2 functions
● Parameterizable minimum shutdown speed to be monitored (p9368/p9568)
Overview of important parameters (see SINAMICS S110 List Manual)

● p9546 SI Motion speed limit n_x (CPU 1)
● p9348 SI Motion SAM actual speed tolerance (CPU 2)
● p9548 SI Motion SAM actual speed tolerance (CPU 1)
● p9368 SI Motion SAM speed limit (CPU 2)
● p9568 SI Motion SAM speed limit (CPU 1)

– The maximum speed increase after SS1 / SS2 is triggered is derived from the
effective acceleration (a) and the duration of the acceleration phase.
– The duration of the acceleration phase is equivalent to one monitoring clock cycle
(p9300/p9500) MC (delay from detecting an SS1 / SS2 until n
Actual speed SAM = acceleration * acceleration duration
The following setup rule is derived thereof:
– For linear axes:
SAM tolerance [mm/min] = a [m/s
– For rotary axes:
SAM tolerance [rpm] = a [rev/s
The SAM tolerance value entered should be approx. 20% higher than the calculated
value.
