8.8 Identification/Optimization "ALM > Infeed/Configuration"
Introduction
On identification of the ALM, control optimization in the ALM is also carried out. Here, the
inductance and capacity of the DC link are determined and the optimum control data
determined for the set-up converter.
Identification can only be performed after the controller and the drive have been put into
operation.
Procedure for automatic identification of the ALM
Identification of the ALM is performed automatically by the system in the current SINAMICS
versions as soon as the first drive has been commissioned and enable terminal X122.1
activated. An internal optimization sequence is started automatically; it takes appox. 20
seconds to complete.
During this optimization sequence, enable terminal X122.1 should not be deactivated;
otherwise the optimization would be aborted. If optimization is aborted, identification may be
carried out manually at a later stage by the user.
Procedure for manual identification of the ALM
Identification of the ALM is carried out as follows:
1. Disconnect release (AUS1) ALM (X122.1) by commissioner.
2. Select machine data for the infeed (ALM) in the menu "Commissioning > Machine data >
3. Initiate identification on the ALM: p3410 = 5.
4. Connect release ALM (release has to remain pending during the execution of the first
5. ALM controller data are reset automatically and power supply identification starts.
6. After identification has occurred, p3410 is automatically written to 0 and the values are
7. Disconnect release ALM (X122.1) by commissioner.
8. The optimized ALM data are saved automatically. The data does not need to be saved
