type and severity of the occurred event. System events which have been
categorized in this way lead to the reactions listed in the following table.
Stop category
Priority
Reaction
STOP 0
High
Events of the category “Stop 0” are immediately signaled as errors and immedi‐
ately shut down the self-contained servo-hydraulic linear axis. These events
must be acknowledged after the cause has been eliminated.
Stop 1
High
Events in the category “Stop 1” are immediately signaled as errors. In contrast
to the “Stop 0” category, the self-contained servo-hydraulic linear axis can in
principle still be used for setting a safe state. After a certain time has elapsed
or after completion of the abort reaction, switching from “Stop 1” in to “Stop
0“ takes place automatically. These events must be acknowledged after the
cause has been eliminated.
Warning
Low
Events of the category “Warning” are only indicated and have an effect on the
self-contained servo-hydraulic linear axis in exceptional cases only. These
events are automatically reset when the cause has been eliminated. Warnings
that are only present temporarily are signaled for a parameterizable minimum
time (e.g. 5 s, specific to the application at hand).
Message
Low
Events of the category “Message” are only signaled and have no effect on the
self-contained servo-hydraulic linear axis. These events are automatically re‐
set. Messages that are present only briefly are displayed for a certain, configu‐
rable minimum time (e.g. 5 s, specific to the application at hand).

Event management
The warning and error events which are recognized by the self-contained ser‐
vo-hydraulic linear axis can basically be divided into four groups:
●
Drive controller error (from firmware)
●
Drive controller warning (from firmware)
●
Application error (from application software)
●
Application warning (from application software)
The resulting diagnostic messages are indicated at the control panel of the
drive controller. For a functional description of the control panel, refer to the
relevant documentation, see
chapter 1.2 "Required and supplementary doc‐
Drive controller errors
If a drive controller error occurs, a diagnostic message "Fxxxx" is generated,
followed by a diagnostic text, and the drive motor is immediately switched to
the torque-free state. Within the software, this state is signaled with a mes‐
sage code and the error output is set.
Drive controller warning
When a drive controller warning occurs, the diagnostic message "Exxxx" is
generated, followed by a diagnostic text. The self-contained servo-hydraulic
linear axis keeps on working normally in this state. Within the software, this
state is signaled with a message code and the warning output is set (if config‐
ured).
Application error
If an application error occurs, diagnostic text number Dxxxx is generated - fol‐
lowed by a diagnostic text, the self-contained servo-hydraulic linear axis is
immediately switched to the torque-free state and the digital error output is
set (if configured).
Application warning/message
If an application-specific warning or message occurs, the diagnostic message
“Bxxxx" is generated, followed by a diagnostic text. The system keeps on
working normally in this state. The digital warning or message output is set (if
