8.7 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
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.
● Optimization runs
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").
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
"Commissioning using the BOP20") operator panel
● Complete the quick commissioning with p3900 = 3 (calculations are performed, p10 and
p3900 are reset to 0)
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").
