4.7 Basic parameterization of the drive objects
Requirements:
● Startdrive is in online mode.
● Operation has been enabled.
● The SERVO type is set for the drive axis.
● The speed controller is active.
● Operation with encoder has been set.
● No measuring function is active.
Assume master control
You require master control over the selected drive for Auto Servo Tuning. Master control has
to be activated before the optimization measurements are started.
1. Click "Activate" at "Master control".
The "Activate master control" message window opens.
2. Read the warning carefully and check the value for the monitoring time.
The monitoring time specifies the time during which the connection from the PC to the
drive is monitored cyclically. The minimum value is 1000 ms.
3. Click "Continue" to confirm the monitoring time.
The message window closes. The "Auto Servo Tuning" screen form then becomes active.
Making the optimization settings
You can make the optimization settings before or after activating the master control:
1. Click "Measured signals".
The "Measured signals" dialog opens:
2. Enter the required values in this dialog:
– Amplitude
– Offset
Note
Offset settings
For axes that do not turn endlessly, you are responsible for observing any existing axial
stroke limitations during the measurement. The larger the offset, the longer the distance
traveled. The axis should be measured within its specific working range.
If required, you can reject the values that have just been recorded and display the old
values again via the "Reset values" button.
