● The flux is increased further until the flux setpoint in p1570 has been reached.
● The field-producing current setpoint is reduced by means of a flux controller with P gain
(p1590) and the parameterized smoothing factor (p1616).
Notes
When quick magnetization is selected (p1401.6 = 1), smooth starting is deactivated internally
and alarm A07416 displayed.
When the stator resistance identification function is active (see p0621 "Identification of stator
resistance after restart"), quick magnetization is deactivated internally and alarm A07416
displayed.
The parameter does not work when combined with the "flying restart" function (see p1200),
i.e. flying restart is performed without quick magnetization.
Alarms and faults
Flux controller configuration
When a function controlled using parameters p1401 and p0621 is activated, the system
checks whether any other incompatible function has already been selected. If this is the
case, alarm A07416 is displayed with the number of the parameter that is incompatible with
that of the configuration (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) for smooth starting (p1401.0)
2 = quick magnetization (p1401.6) for flux build-up control (p1401.2)
3 = quick magnetization (p1401.6) for Rs identification (stator resistance identification) after
restart (p0621 = 2)
Remedy:
● For fault cause 1:
– Deactivate smooth starting: p1401.0 = 0
– Deactivate quick magnetization: p1401.6 = 0
● For fault cause 2:
– Deactivate flux build-up control: p1401.2 = 0
– Deactivate quick magnetization: p1401.6 = 0
● For fault cause 3:
– Change Rs identification parameter settings: p0621 = 0, 1
– Deactivate quick magnetization: p1401.6 = 0
