Line Supply And Dc Link Identification Routine For Smart Infeed Booksize - Siemens SINAMICS S120 Function Manual

3.3.1

Line supply and DC link identification routine for Smart Infeed Booksize

Function description
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 or the components connected to the DC link change (e.g. after
installation of the equipment at the customer's site or after expanding the drive line-up), the
supply/DC-link identification routine should be repeated with p3410 = 5. Only then can it be
guaranteed that the infeed unit operates with an optimum controller setting.
When the identification function is activated, alarm A06400 is output.
Note
While the identification routine is running, it is not permissible that other loads are switched-in/
switched-out.
Note
The line supply and DC link identification routine is not permissible for Smart Line Modules of
the Chassis type.
Identification methods
The following identification types are available:
● p3410 = 4: Identify and save controller setting with L adaptation
An identification run for the total inductance and DC link capacitance is initiated when the
pulses are next enabled (2 measuring routines with different current magnitudes). Data
determined during the identification routine (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 of the parameters for the infeed
unit are then automatically stored in a non-volatile memory. The infeed unit continues to
operate without any interruption with the new controller parameters.
● p3410 = 5 (preferred): Reset, save ID and controller setting with L adaptation
Unlike p3410 = 4, the parameter values for line inductance and DC link capacitance are
reset before the first identification run (p3421 = p0223 and p3422 = p0227).
Note
Identification using p3410 = 5 should preferably be used.
P3410 = 0 is automatically set when an identification routine is successfully completed.
For additional identification methods, see the SINAMICS S120/S150 List Manual.
It may be necessary to reset the closed-loop controller to the factory settings if an identification
run was unsuccessful, for example.
