SINAMICS G120 Control Units CU240B/E-2 Parameter Manual (LH11), 01/2011
Description: Setting to save parameters in the non-volatile memory.
Value: 0: Inactive
1: Save drive object
10: Save in non-volatile memory as setting 10
11: Save in non-volatile memory as setting 11
12: Save in non-volatile memory as setting 12
Dependency: Refer to: p1960, r3996
Caution: If a memory card (optional) is inserted, the following applies:
The parameters are also saved on the card and therefore overwrite any existing data!
Caution: 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).
Notice: Writing to parameters is inhibited while saving.
The progress while saving is displayed in r3996.
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 lon-
ger 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 the cyclic communication is active for both PROFIdrive interfaces, then the reset is executed after completing
both cycle communications.
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 fol-
lowing:
p0972 = 0? --> The reset was successfully executed.
p0972 > 0? --> The reset was not executed.
