ctrlX SAFETY "SafeMotion"
● The duration of the transition is monitored (cf. "P‑0‑3280.0.2" or
"P‑0‑3280.0.3"). When the monitoring function is triggered, this causes
an error reaction which decelerates the drive system. The corresponding
error message is "F7050 Maximum transition time exceeded or "F8350
Maximum transition time exceeded“.
●
The deceleration during the transition is monitored via the
safety function "Safely-monitored deceleration (SMD)". When the
monitoring function is triggered, this causes an error reaction
which decelerates the drive system. The corresponding error mes-
sage is "F7051 Safely-monitored deceleration exceeded“ or "F8351
Safely-monitored deceleration exceeded“.
●
The transition function "Safe stop 2" is selected via the active "SafeMotion"
profile using the parameter “P-0-3264, SMO: Safety function selection".
●
The state of the transition function "Safe stop 2" is displayed via parameter
“P-0-3264.0.1, SMO: Safety function status“.
Parameters involved
The following parameters are used in conjunction with the transition function
"Safe stop 2 (SS2)":
● P‑0‑3238, SMO: Active velocity threshold
● P‑0‑3255, SMO: Velocity threshold for Safe standstill
● P‑0‑3261.0.1, SMO: State machine control word, functional
●
P‑0‑3263.0.1, SMO: Configuration of stopping process
●
P‑0‑3264, SMO: Safety function selection
●
P‑0‑3264.0.1, SMO: Safety function status
● P‑0‑3280.0.1, SMO: Configuration of operation mode transitions
● P‑0‑3280.0.2, SMO: Max. Transition time normal oper. to safe standstill
● P‑0‑3280.0.3, SMO: Max. Transition time between safe operating states
Diagnostic messages involved
The following diagnostic messages can be generated in conjunction with the
safety function "Safe stop 2 (SS2)":
● C0214 SMO: Incorrect configuration
●
F7050 Maximum transition time exceeded
●
F7051 Safely-monitored deceleration exceeded
● F7052 Selected target velocity exceeded
● F8350 Maximum transition time exceeded
● F8351 Safely-monitored deceleration exceeded
With the transition function "Safe stop 2 (SS2)" activated, the display of the
drive controller panel does not show any specific message.
Transition function
Configuring the transition function
To use the transition function "Safe stop 2 (SS2)",
it has to be configured via the parameter “P-0-3280.0.1,
SMO: Configuration of operation mode transitions“ during the commissioning
of safety technology.
Selecting the transition function
The transition function "Safe stop 2 (SS2)" can be activated
via the active "SafeMotion" profile using the parameter “P-0-3264,
SMO: Safety function selection", when the following conditions have been ful-
filled:
