Faults Faults indicate to the user positioning motor states where the motor
can only be shut down or switched into a no current condition.
How does the DP master evaluate faults?
1. By reading the status signal ZSW.3 (fault present)
2. By reading P947 (3B3
3. By reading P954 (3BA
How are the faults acknowledged?
1. Remove the cause of this fault (refer to Chapter 6.2.2).
2. STW.7 (reset the fault memory) = set 0/1 signal edge.
3. Set the STW.0 (ON/OFF 1) to "0" and "1".
Note
If the status signal ZSW.3 (fault effective) is not "0", then the above
points should be repeated for the fault or faults that are still present.
SIMODRIVE POSMO A can only resume normal operation after all of
the faults that are present have been acknowledged.
The faults are described in detail in Chapter 6.2.2.
