The Object Directory dialogue box shows a tree view of all parameters (CanOpen objects) of the
drive module. Via this structure, you can directly access all objects and read and / or write the
parameter according to the respective characteristics. A description of all objects can be found in the
“Object Directory” chapter on page 78. Only users experienced in CanOpen standards may use this
dialogue box in order to set parameters. All other users shall realise the setting of parameters via the
“Commissioning” dialogue box (see Commands of the Commissioning menu on page 33).
The tree view on the left side is subdivided into Communication (DS301), Device Profile (DS402) and
Manufacturer-Specific Objects. On the right side, the characteristics and the content of the currently
selected object are displayed. By means of the <Assume> button, you can realise changes in the
current parameters. <OK> also confirms the current change and closes the dialogue box.
The “ Always update ” option has the effect that the value of the currently selected parameters is read
about 5 times per second from the drive module (in case of an enabled online mode).
Via the “ Save current values in module ” button, you can permanently store the currently set values
(set of parameters) in the drive module (the storing of individual parameters is not possible).
