Warnings indicate to the user motor statues that do not necessarily
mean that operation must be interrupted.
How does the DP master evaluate warnings?
1. By reading the status signal ZSW.7 (warning effective)
A ”1” signal indicates that there is at least 1 warning present.
2. By reading P953 (3B9hex)
The parameter value indicates, bit–coded, which warnings are present
(refer to Table 6-2 and Chapter 6.2.2).
3. By reading P954 (3BAhex) (from SW 1.4)
The parameter value indicates, bit–coded, which supplementary
information is present (refer to Table 6-2 and Chapter 6.2.2).
Note
If the status signal ZSW.7 (warning effective) is not ”0”, then the above
points must be repeated for the warning or warnings that are still
present.
Warnings are described in detail in Chapter 6.2.2.
For faults and warnings, measures are described which can be applied
to remove/withdraw the fault/warning.
In this case, one of the possibilities specified is to replace the positioning
motor. For POSMO A – 300 W, it is also possible, corresponding
to the information given as counter–measure, to only change the drive
unit.
Replacing the positioning motor
––> refer to Chapter 7.1
Replacing the drive unit (only POSMO A – 300 W)
––> refer to Chapter 7.3.2
