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). The data
acquired (r3411 and r3412) is entered into p3421 and p3422. At the same time, the
parameters for current controller adaptation are recalculated (p3620, p3622). 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: 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. The identification can be carried
out for both Active Line Modules of the Chassis format and for ALMs of the Chassis-2 format.
● p3410 = 6: Robust controller setting for Active Line Modules the Chassis-2 format
(ALM Chassis-2)
For ALM Chassis-2, you can use p0220 ≥ 110 to select the corresponding
Active Interface Modules of the Chassis-2 format (AIM Chassis-2) automatically and carry
out an automated controller setting with p3410 = 6. During the automated controller setting,
the value of the DC link is determined in a substantially shortened measurement. All of the
other controller parameters are already preset by setting p3410 = 6.
The following advantages and disadvantages must be observed:
– Adjustments relating to the controller parameters and grid identification are not required
– Unlike identification over p3410 = 5, the automated controller setting leads to losses in
P3410 = 0 is automatically set when an identification routine is successfully completed.
Additional identification methods are listed in the SINAMICS S120/S150 List Manual.

Active Infeed open-loop control

Description
The Active Line Module can be controlled via the BICO interconnection using terminals or the
fieldbus. The operating status is indicated on the operating display r0002. The missing enable
signals for operation (r0002 = 00) are mapped in parameter r0046. The EP terminals (enable
pulses) must be connected in accordance with the manual of the corresponding power units.
The drive unit must have been commissioned for the first time.
Acknowledging faults
Faults that are still present but the causes of which have been rectified can be acknowledged
using a 0/1 edge at the "1st acknowledge faults" signal (p2103).
