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 has to be saved as follows in a non-volatile manner on the CompactFlash card so
that it is available the next time the drive is switched on.
● Save parameters - device and all drives
p0977 = 1; automatically reset to 0
● Save the parameters with STARTER
See "Copy RAM to ROM" function
Resetting parameters
The parameters can be reset to the factory setting as follows:
● Reset parameters - current drive object
p0970 = 1; automatically reset to 0
● Reset parameters - all parameters drive object "Control Unit"
p0009 = 30 parameter reset
p0976 = 1; automatically reset to 0
Access level
The parameters are subdivided into access levels. The SINAMICS S List Manual specifies in
which access level the parameter is displayed and can be changed. The required access
levels 0 to 4 can be set in p0003.
Table 12-1 Access levels
Access level Remark
0 User-defined
1 Standard Parameter from the user-defined list (p0013)
Parameters for the simplest operator functions (e.g. p1120 = ramp function
generator ramp-up time).
2 Extended Parameters to handle the basic functions of the device.
3 Expert Expert knowledge is already required for this parameter (e.g. knowledge
about BICO parameterization).
4 Service Please contact your local Siemens office for the password for parameters
with access level 4 (Service). It must be entered into p3950.
Note
Parameter p0003 is CU-specific (belongs to Control Unit).
