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
See "Copy RAM to ROM" function
● Saving parameters
p0977 = 1; automatically reset to 0
Note
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).
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
device in a non-volatile memory (ROM) of the device and which can be deleted using
p0976=1 (restore factory settings), the following data also belongs 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 is deleted from the
ROM as follows:
p0009 = 30
p0976 = 200
