SINAMICS G120 CU230P-2 Control Units
124 List Manual (LH9), 04/2014, A5E33838102B AA
11: Save in non-volatile memory as setting 11
12: Save in non-volatile memory as setting 12
Dependency: Refer to: p0970, p1960, r3996
Caution: If a memory card (optional) is inserted – and the USB interface is not used, the following applies:
The parameters are also saved on the card and therefore overwrite any existing data!
Notice: The Control Unit power supply may only be powered down after data has been saved (i.e. after data save has been
started, wait until the parameter again has the value 0).
Writing to parameters is inhibited while saving.
The progress while saving is displayed in r3996.
Note: Parameters saved with p0971 = 10, 11, 12 can be loaded again with p0970 = 10, 11 or 12.
Identification and maintenance data (I&M data, p8806 and following) are only saved for p0971 = 1.
Description: Sets the required procedure to execute a hardware reset for the drive unit.
Value: 0: Inactive
1: Hardware-Reset immediate
2: Hardware reset preparation
3: Hardware reset after cyclic communication has failed
Danger: It must be absolutely ensured that the system is in a safe condition.
The memory card/device memory of the Control Unit must not be accessed.
Note: If value = 1:
Reset is immediately executed and communications interrupted.
After communications have been established, check the reset operation (refer below).
If value = 2:
Help to check the reset operation.
Firstly, set p0972 = 2 and then read back. Secondly, set p0972 = 1 (it is possible that this request is possibly no
longer acknowledged). The communication is then interrupted.
After communications have been established, check the reset operation (refer below).
If value = 3:
The reset is executed after interrupting cyclic communication. This setting is used to implement a synchronized reset
by a control for several drive units.
If cyclic communication is not active, then the reset is immediately executed.
After communications have been established, check the reset operation (refer below).
To check the reset operation:
After the drive unit has been restarted and communications have been established, read p0972 and check the
following:
p0972 = 0? --> The reset was successfully executed.
p0972 > 0? --> The reset was not executed.
Description: Displays the parameters that exist for this drive.
Dependency: Refer to: r0981, r0989
Note: The existing parameters are displayed in indices 0 to 298. If an index contains the value 0, then the list ends here. In
a long list, index 299 contains the parameter number at which position the list continues.
