Many objects in the object dictionary can be saved and then automatically reloaded the next time the controller is switched on or reset. Furthermore, the saved values are also retained following a firmware update.
Only entire collections of objects (referred to in the following as categories) can be saved together; individual objects cannot be saved.
- Communication: Parameters related to external interfaces, such as PDO configuration etc.
- Application: Parameters related to operating modes.
- Cutsomer: Parameters that are written and read by the customer/user only and are ignored by the controller firmware.
- Drive: Parameters related to the motor and the sensors (BLDC/Stepper, Closed/Open Loop…). Some are set and saved by auto setup.
- Tuning: Parameters related to motor and encoder that are set either by auto setup or that can be found in the data sheets, e.g., pole pairs and maximum current.
If an object is not assigned one of these categories, it cannot be saved, e.g., statusword and all objects whose value is dependent on the current state of the controller.
The objects in each category are listed below. In chapter Description of the object dictionary, the corresponding category for each object is also specified.

Starting the save process
- Saving may take a few seconds. Under no circumstances may you interrupt the voltage supply while saving. The state of the saved objects is otherwise undefined.
- Always wait until the controller has signaled that the save process has been successfully completed with the value "1" in the corresponding subindex in object 1010h.
There is a subindex in object 1010h for each category. To save all objects of this category, the value "65766173h" must be written in the subindex. 1 The controller signals the end of the save process by overwriting the value with a "1".
The following table shows which subindex of object 1010h is responsible for which category.
|01h||All categories with the exception of 06h (Tuning)|
Discarding the saved data
|01h||All categories (reset to factory settings) with the exception of 06h (Tuning)|
The saved objects are subsequently discarded; the change does not take effect until after the controller is restarted. You can restart the controller by entering the value "746F6F62h" in 2800h:01h.
- Objects of category 06h (Tuning) are determined by Auto setup and are not reset when resetting to factory settings with subindex 01h (thereby making it unnecessary to again perform an auto setup). You can reset these objects with subindex 06h.
Verifying the configuration
Object 1020h can be used to verify the configuration. It acts as a modification marker similar to common text editors: as soon as a file is modified in the editor, a marker (usually an asterisk) is added.
- An external tool or master configures the controller.
- The tool or master sets the value in object 1020h.
- The tool or master activates the saving of all objects 1010h:01h = 65766173h. The date and time in object 1020h are also saved.
