Behaviour in the case of active software limit positions

Note!
The "travel commands" mentioned in the following description are no speed setpoint
selections. In the "Speed follower" and "Position follower" operating modes, an
acknowledged software limit position error ensures that traversing to the impermissible
travel range remains possible afterwards. This is because in these two operating modes,
there is no preview of whether a software limit position is approached with a setpoint
selection.
If the software limit positions are active, travelling commands that would result in the exit from the
permissible travel range can no longer be executed.
In positioning operation, the warning "Ck14: target position outside SW limit position" is output for
target positions that are outside of the software limit positions. The positioning process is not
aborted, but is executed to the software limit position instead of to the target position outside the
software limit position.
If the drive is already outside the permissible travel range and the software limit positions have
been activated, only travel commands that result in the drive moving back into the permissible
travel range can be executed.
If the software limit positions are active, and one of the software limit positions is overtravelled, in
the Lenze setting the "TroubleQuickStop" error response is triggered: Irrespective of the setpoint
selection, the drive is brought to a standstill in the deceleration time set for the quick stop function.
Depending on the error response parameterised, the drive can then only be traversed again after the
error has been acknowledged.

Error and status messages of the positioning sequence control

The application provides the LS_SetError_1 SB for the purpose of error handling.
• The application can trip up to four different user error messages with parameterisable error IDs
and error responses via the four boolean inputs of the LS_SetError_1 SB.
• In the "Position Sequencer" technology application, the inputs of the LS_SetError_1 SB are
linked with error/status outputs of the L_Sequencer_1 FB.
• You can gather the application-specific meaning of the user errors as well as the preset response
from the following table:
