With the “load” command, the default values for the respective objects are saved in the RAM (volatile
memory) of the encoder. This means that after the encoder has been switched off and on, these default
values are lost again. In order to save the default values in the Eeprom (non-volatile memory) of the encoder,
it is additionally necessary for the “save” command to be written to sub-index 1 of object 1010

.
13.3 EDS file
The EDS file is the electronic description of the object directory of the ATM60-Cxx. The commissioning
instructions represent the description of the object directory in written form.
The description of the object directory is needed for the configuration and operation of the ATM60-Cxx.
The EDS file is read in by a configuration tool. Using the entries in the EDS file, the configuration tool
provides the user with all the available objects in this device.
As a result, a device can be configured easily without any prior knowledge of its object directory.
