If the setting should be maintained in the case of a power failure, the changes have to be saved, as
described in section (
10.2.4.4
Setting the Sending Cycle for the Position Data
The position data are sent cyclically by the device, therefore the device has to be in the Operational Mode (
10.2.6.1).
The settings of the cycle duration takes place in the device profile DS406 in the object 1800h, Sub-index 5 and
for devices with DS417 profile in object 1906h, Sub-index 5.

Change into the Operational or Pre-operational Mode, if necessary.

VV = 18h (DS406), 19h(DS417)
YY = LSB of cycle time in milliseconds

scribed in section (
10.2.5
Saving the Parameters
In the normal case the settings are lost at power failure. In order to avoid this, they need to be saved according
to the following procedure.
1.
Change into the Operational or Pre-operational Mode, if necessary.
