3.2 Diagnostics via STARTER
Measuring functions
1. Speed controller reference frequency response (downstream of the speed setpoint filter)
2. Speed controller path (excitation downstream of current setpoint filter)
3. Speed controller interference frequency response (fault downstream of the current
4. Speed controller reference frequency response (upstream of the speed setpoint filter)
5. Speed controller setpoint change (downstream of the speed setpoint filter)
6. Speed controller disturbance step change (fault downstream of the current setpoint filter)
7. Current controller reference frequency response (downstream of the current setpoint
8. Current controller setpoint change (downstream of the current setpoint filter)
Starting/stopping the measuring function
With the corresponding measuring function parameter settings (e.g. offset), the motor can
"drift" and travel to its end stop.
The movement of the drive is not monitored while the measuring function is active.
To start the measuring function:
1. Set the preconditions for starting the measuring function.
2. Select the drive in the project tree.
3. In the project tree, double-click on "Drive" > "Commissioning" > "Measuring function".
4. Set the required measuring function.
5. Then download the settings to the target device by clicking on the symbol
6. Start the function generator ("Start measuring function" button).
To stop the measuring function:
● The measuring function runs for a limited time and then automatically stops.
● "Stop measuring function" button
Parameterization
The "Measurement function" parameterizing screen form is selected via the following icon in
the toolbar of the STARTER commissioning tool.
