Alarms and faults
Flux controller configuration
When a function controlled by parameter p1401 and p0621 is activated, the system checks
whether any other incompatible function is already selected. If this is the case, alarm A07416
is displayed with the number of the parameter which is incompatible with the configuration
parameter (i.e. p0621 or p1401).
As these are data-set-dependent parameters (p1401 is DDS-dependent and p0621 MDS-
dependent), the number of the data set is also specified in the alarm value.
The flux control configuration (p1401) settings are inconsistent.
Fault codes:
1 = quick magnetization (p1401.6) and smooth starting (p1401.0)
2 = quick magnetization (p1401.6) and flux build-up control (p1401.2)
3 = quick magnetization (p1401.6) and Rs identification (stator resistance identification) after
restart (p0621 = 2)
Remedy:
● For fault cause 1:
● For fault cause 2:
● For fault cause 3:
Flux controller output limited
If the current limit p0640[D] is set very low (below the rated magnetizing current value in
p0320[M]), the parameterized flux setpoint p1570 [D] might not be reached at all.
As soon as the time in p0346 (magnetization time) is exceeded, fault F07411 is output.
Generally, the magnetization time is significantly longer than the flux build-up time
associated with quick magnetization.
