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 retentively on the memory card, as described below, 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 of the drive object "Control Unit" (CU_*)
p0009 = 30 parameter reset
p0976 = 1; automatically reset to 0
Access level
The parameters are subdivided into access levels. The SINAMICS S120/S150 List Manual
specifies the access level in which the parameter is displayed and can be changed. The
required access levels 0 to 4 can be set in p0003.
Table 13- 1 Access levels
Access level Remark
0 User defined Parameters from the user-defined list (p0013)
1 Standard Parameters for the simplest operator functions (e.g. p1120 = ramp-function
generator ramp-up time)
2 Advanced 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 Expert knowledge is also required for these parameters. Parameters of this
access level are no longer password-protected as of firmware V5.1.
Note
Parameter p0003 is CU-specific (available on the Control Unit).
