Line supply and DC link identification routine for Smart Infeed Booksize

The characteristic line supply and DC link quantities are determined using the automatic
parameter identification routine. They provide the basis to optimally set the controllers in the
Line Module.
Note
If the line supply environment changes or the components connected to the DC link (e.g.
after installation of the equipment at the customer's site or after expanding the drive line-up),
the line supply/DC link identification routine should be repeated with p3410 = 5. Only then
can it be guaranteed that the infeed operates with an optimum controller setting.
When the identification function is activated, alarm A06400 is output.
CAUTION
The line supply and DC link identification routine is not permissible for Smart Line Modules
of the Chassis type.
Identification methods
For additional identification methods, see the SINAMICS S120/S150 List Manual.
● p3410 = 4: An identification run for the total inductance and DC link capacitance is
● p3410 = 5: The same measurements and write operations are always carried out for
p3410 is automatically set to 0 when one of the two identification routines (p3410 = 4 or
p3410 = 5) completes successfully.
Note
Identification using p3410 = 5 should preferably be used.
It may be necessary to reset the closed-loop controller to the factory settings if an
identification run was unsuccessful, for example.

initiated when the pulses are next enabled (two measuring routines with different current
magnitudes). Data determined during identification (r3411 and r3412) is entered into
p3421 and p3422 and the controller is recalculated. At the same time, the parameters for
current controller adaptation are determined (p6320, p6322). All infeed parameters are
then automatically stored in non-volatile memory.
The infeed continues to operate without interruption on the new controller parameters.
p3410 = 4. However, before the first identification run, the parameter values for line
inductance and DC link capacitance are reset (p3421 = p0223 and p3422 = p0227) and
the coarse settings are made for the controller.
