Note: A factory setting run can only be started if p0010 was first set to 30 (parameter reset).
At the end of the calculations, p0970 is automatically set to 0.
Parameter reset is completed with p0970 = 0 and r3996[0] = 0.
The following generally applies:
One index of parameters p2100, p2101, p2118, p2119, p2126, p2127 is not reset, if a parameterized message is
precisely active in this index.
Description: Setting to save parameters in the non-volatile memory.
When saving, only the adjustable parameters intended to be saved are taken into account.
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!
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.
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.
