ctrlX SAFETY "SafeMotion"
● When the deceleration monitoring is triggered, this causes an error
reaction which decelerates the drive system. The corresponding error
message is "F7051 Safely-monitored deceleration exceeded“ or "F8351
Safely-monitored deceleration exceeded“.
It is also possible to configure that the axis may move by a parameterizable
distance before the error F7051 or F8351 is generated. The warning E3151
is triggered during this motion.
●
The transition function "Safely-monitored deceleration" is selected
via the active "Safe Motion" profile using the parameter “P-0-3264,
SMO: Safety function selection".
●
The state of the transition function "Safely-monitored deceleration" is dis-
played via parameter “P-0-3264.0.1, SMO: Safety function status“.
Transition function
Basic principle
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.
Configuring the transition function
To use the transition function "Safely-monitored deceleration", the
function has to be configured via the parameter "P‑0‑3280.0.1,
SMO: Configuration of the operation mode transitions“ and "P‑0‑3263.0.1,
SMO: Configuration of stopping process“.
The active monitoring functions depend on the parameterization of the axis,
as well as on the selected safety function. The tables below show when the
different types of monitoring are active and which error is generated when the
monitoring function triggers.
