ctrlX SAFETY "SafeMotion"
110 / 302
Transition functions
● By activating the SOS function after the deceleration process has been com-
● By deselecting the transition function via the active "SafeMotion" profile
● When a safety technology error occurs
● By selecting the safety function "STO" or "SS1"
In the case of a drive-controlled operation mode transition, the started deceler-
ation process is continued by the standard firmware, even if the safety function
is deselected.
8.5.3
Safely-monitored deceleration (SMD)
Brief description
The transition function "Safely-monitored deceleration" (SMD) uses dual-
channel monitoring to detect whether the actual velocity of the drive, given
a change in the operating status or given an error reaction, is within a parame-
terized velocity envelope curve.
Four
"Safely-monitored deceleration (SMD)" are available.
Features
The function has the following features:
● The safety function is intended for safety-relevant applications up to
● The transition function can be used in drive systems equipped with the

Furthermore, the transition can be performed in two ways:
– "Drive-controlled", i.e. the transition of the drive is carried out by the
standard firmware, and the safety technology monitors the transition
process or
– "NC-controlled", i.e. the higher-level control unit carries out the transition
of the drive by adjusting the command value system, and the safety tech-
