Drive optimization

Basic information
The individual control loops must be optimized when commissioning a drive.
4 control loops must be set or optimized:
● Field current closed-loop control
● Armature current closed-loop control
● Speed control
● EMF closed-loop control
SINAMICS DCM supports this task in 2 ways.
● Quick commissioning
● Optimization runs
Quick commissioning
Procedure
● Start the quick commissioning with p10 = 1 (= factory setting)
● Set all of the important parameters (see e.g. commissioning steps in Chapter
● Complete the quick commissioning with p3900 = 3 (calculations are performed, p10 and
Commissioning using the BOP20 operator panel:
This procedure is explained for the commissioning steps in Chapter "Commissioning using
the BOP20" operator panel.
Commissioning using the AOP30 operator panel:
Quick commissioning is completed (p3900 = 3) as part of the final confirmation. (see Chapter
"Commissioning using the AOP30 operator panel", Section "Complete drive
commissioning").

The controller parameters are calculated from the rated data of the motor and the power
unit. No measurements are made. Only the parameters for the field current closed-loop
control, the armature closed-loop control and the speed closed-loop control are
determined. The parameters set during the quick commissioning allow reliable drive
operation in the majority of cases.
The controller parameters are determined from the rated data of the motor and the power
unit and by evaluating measurement results. The parameters of all 4 control loops are
determined. The parameters set using the optimization runs can be kept in the majority of
cases. In exceptional cases, manual post-optimization is necessary (see Chapter
"Manual optimization").
