Safety functions

An important aspect of functional safety is that the safety functions are completely self-contained carried out by the safety modules without the need for additional programming or measures.
SS0 SS1 SS2
SOS SLS SDI
The safety modules provide the following safety functions:
  • SS0 / STO (Safe Stop Category 0)
  • SS1 (Safe Stop Category 1)
  • SS2 (Safe Stop Category 2)
  • SOS (Safe Operating Stop)
  • SLS (Safely Limited Speed)
  • SDI (Safe Direction)
The SS0 / STO safety function is included as standard in the servo drives. If only this is required, no additional safety modules are required.
