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 the following
Chapter "Manual optimization").

Quick commissioning

NOTICE
Both drive optimization types assume that all of the parameters are at their factory settings
before the drive is optimized.
This is the case when the device is originally shipped. If the parameters have already been
changed, or if you are not certain that all of the parameters are at their factory settings, then
run the "Restore factory setting" function!
With the basic operator panel BOP20:
(1)p0009 = 30
(1)p0976 = 1
SINAMICS DCM resets all of the parameters to the factory setting, and executes a power
on. The parameters must then be permanently saved by pressing the P button for a longer
period of time (at least 3 seconds, however until the display starts to flash).
