Backing up parameters
Proceed as follows to back up the parameters:
1. In the project navigator, select the SINAMICS unit with the drive for which you want to
perform the automatic setting.
2. Select "Target device" > "Copy RAM to ROM" in the context menu.
3. Select "Target device" > "Load CPU / drive unit to PG" in the context menu.
If required, the automatic controller settings can be checked using the measuring functions.
6.16.3 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.
