Note
Service parameters
The service parameters can only be accessed by authorized Siemens personnel.
If a particular setting is not possible or special application-specific supplementary conditions
are present, individual steps can also be omitted.
Example 2: Faults during operation when loading the infeed, operating on a "normal" supply
Power failure (F6200, A6205), DC link overvoltage (F30002)
Following procedure:
1. Exclude other sources of fault: e.g. actual power failure, wiring fault, correct supply data
setting (p0210, p0211)
2. If 1. was not successful, then in addition:
P3463 infeed unit supply angle change phase failure = 15 to 30°
→ perform the load test.
3. If 2. was not successful, then in addition:
Change the controller gain p3560 = 10 to 300%
and if required the integral time p3562 = 50% (Vdc controller)
→ perform a load test
4. If 3. was not successful, then in addition:
Change voltage setpoint p3510, increase or decrease depending on fault profile and
application
→ perform a load test
5. If 4. was not successful, then in addition:
p3530 Infeed current limit, motoring = rated Active Infeed current (r0207).
p3531 Infeed current limit, regenerating = rated Active Infeed current (r0207).
→ perform a load test
