Messages to the user
The messages of the SINAMICS Safety Integrated Extended functions are displayed as
Error in the TO DB of the axis (StatuswordSafety).
● Error ID 8140: Safety alarm in the drive
A new event is present in the safety message buffer of the drive.
● Error ID 8141: SINAMICS Safety Integrated Extended Function is selected
If the SS2/SOS/SLS safety functions are selected, error ID 8141 is signaled. When an
automatic transition to SOS is carried out as part of SS2 selection, then error ID 8141 will
not be signaled. The message is for information only.
● Error ID 8142: SINAMICS Safety Integrated Extended Function is deselected
If the SS2/SOS/SLS safety functions are deselected, error ID 8142 is signaled. When
SS2 is deselected, error ID 8142 is signaled only once, even though this process also
deselects SOS. The message is for information only.
Note
The errors are displayed on the Axis technology object only when the support is
configured for the SINAMICS Safety Integrated extended functions.
When STO and SS1 are selected, only error ID 8010 will be signaled, similar to the basic
functions. For SS1, the error will not be triggered until the braking ramp is complete.
There is no error to signal that the functions have been deselected.
