Automatic Position Controller Setting - Siemens SIMOTION D4x5-2 Commissioning And Hardware Installation Manual

Automatic position controller setting

Introduction
In the "Automatic Controller Setting" screen form, you can select the SINAMICS drive unit and
the drive for which you want to carry out an automatic DSC position controller setting. The
necessary steps for this calculation can be performed from this screen form. The calculated
Kv value is displayed and can then be accepted online in the configuration data of the axis
that is assigned to the drive.
Requirements
In addition to the General requirements for the automatic controller setting, the following
boundary conditions apply for setting the position controller:
● DSC is required for the position controller setting.
Tip:
Activate the project setting "Use symbolic assignment" and select the Standard/Automatic
option for the axis-drive communication when configuring the drives. You automatically use
DSC for the servo drives with these settings.
● The speed controller has already been configured (e.g. with the automatic speed controller
setting).
● At least one axis is connected to the SINAMICS drive (servo).
● An online connection to the SIMOTION device must be established to transfer the results
of the automatic position controller setting.
● The balancing filter is not changed.
● For operation without precontrol, the equivalent time constant of the position controller must
be adjusted manually by the user (PositionTimeConstant = 1/Kv).
● Vibration on the load side is not taken into account for the position controller setting.
Procedure
To perform an automatic setting of the position controller, proceed as follows:
1. Select the "Target system" > "Automatic controller setting" menu command.
2. Select the drive unit and the drive (axis).
3. Select the "Position controller (DSC)" from "Controller selection".
4. Click "Assume control priority" to assume control priority.
5. Click the "Drive on" button to enable the drive.
Perform the steps either in automatic mode or as individual steps.
6. Select the axis data sets to which the Kv factor is to be transferred.
7. Click "Accept values" to transfer the calculated Kv factor to the axis data sets.
8. Disable the drive by clicking the "Drive off" button.
