Infeed

1.2 Smart Infeed

Note

If the line supply environment changes, or the components connected to the DClink (e.g. after installing and mounting the equipment at the customer's site or after expanding the drive group), then 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 S List Manual.

●p3410 = 4: An identification run for the total inductance and DC link capacitance is 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 of the parameters for the Infeed Module are then automatically stored in a non-volatile memory.

The infeed continues to operate without any interruption with the new controller parameters.

●p3410 = 5: The same measurements and write operations are always carried-out for 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.

p3410 is automatically set to 0 after an identification run has been successfully completed.

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.
