Safety-relevant NC variables (OPI) are available in the Safety Integrated mode; to a large
extent, these are mapped using SIC signals.

Block index Name Meaning
S 183 aStopesi Actual Safety Integrated Stop E for any axis.
SEMA 214 vaStopSi Safety Integrated stop.
SEMA 119 safeDesVeloLimit Effective speed setpoint limit in the NC. This is ob‐
tained from a speed setpoint limit in the drive and a
(possibly) active speed setpoint limit in the NC.
SEMA 277 safeAxisType Type of axis-specific safety monitoring functions
(safety axis operating mode).
