3.9.2 Safe speed limitation
The SM301 supports the safe monitoring of a maximum speed (SMS), which is active for all
operating states. Furthermore the monitoring of a safely limited speed (SLS1) can be activated via a
safe input or the safety bus.
From SM301 V1.1 onwards, the following safety functions are additionally supported:
• Safely limited speed 2 (SLS2)
• Safely limited speed 3 (SLS3)
• Safely limited speed 4 (SLS4)
