Saving parameters in a non-volatile memory
The modified parameter values are stored in the volatile RAM. When the drive system is
switched off, this data is lost.
The data must be saved in the non-volatile memory, as described below, so that the
changes are available the next time the drive is switched on.
● Saving parameters with STARTER
● Saving parameters
Resetting parameters
The parameters can be reset to the factory setting as follows:
p0009 = 30
p0976 = 1
After this has been done, p0976 is automatically set to 0 and p0009 is set to 1.
Deleting all user data
In addition to the actual parameter data set, which saves the parameter assignment of the
unit in a non-volatile memory (ROM) of the unit and which can be deleted using p0976=1
(restore factory settings), the following data also belong to the non-volatile user data:
● DCC charts
● The DCC block library
● Additional parameter data sets (see p0802, p0803, p0804)
This data is also saved in the non-volatile memory (ROM). All user data are deleted from the
ROM as follows:
p0009 = 30
p0976 = 200
The operation may take several minutes. The unit automatically powers up during this time.
As a result, the unit in STARTER goes offline. Re-connect with the drive. After this has been
done, p0976 is automatically set to 0 and p0009 is set to 0.

NOTICE
The power supply to the Control Unit may first be switched off only after saving has
finished (i.e. after saving has started, wait until the parameter has the value 0 again).
