Automatic speed controller setting
Characteristics
The automatic speed controller setting has the following features:
● Attenuation of resonances in the speed-controlled system
● Automatic setting of the Kp gain factor and the Tn reset time of the speed controller
● The speed setpoint filter and the reference model are not changed.
Procedure
To perform an automatic setting of the speed controller, proceed as follows:
1. Select the "Target system" > "Automatic controller setting" menu command.
2. Select the drive unit and the drive.
3. Select the "Speed controller" from the "Controller Selection".
4. Click "Assume control priority" to assume control priority.
5. Click the "Drive on" button to enable the drive.
Perform these steps (1 to 4) in automatic mode or as individual steps.
6. Click "Transfer" to transfer the calculated parameter values for the speed controller to the
drive.
7. Disable the drive by clicking the "Drive Off" button.
8. Click "Give up control priority" to give up control priority of the PG/PC.
9. Save the online parameters.
You can now transfer the automatically set parameters to the project.
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.
