Meaning of the diagnostics parameters

Note
Saving diagnostics values
The diagnostics values are written into a non-volatile memory every 15 minutes so that, in
the event of a power failure, only the values of the previous 15 minutes are lost. The values
in the resettable parameters can be set to zero.
• To do this, press the
The values which can be reset can be found in the table in section "Overview of diagnostics
values (Page 206)".

0 ... 4.29E9
In operation, the movements of the actuator are summed up and
displayed in this diagnostics parameter as the number of strokes.
Unit: 100% strokes, i.e. the path between 0 and 100% and back.
0 ... 4.29E9
Every change in direction of the actuator is noted in the closed-
loop controller and added to the number of changes in direction.
0 ... 4.29E9
Every fault is noted in the closed-loop controller with '3. CNT' and
added to the number of fault messages.
Alarm function is activated by means of the "'44.AFCT' Alarm func-
tion (Page 169)" parameter.
0 ... 4.29E9
This value indicates how often the alarm has been triggered.
