Description: Sets the transfer direction and start of data transfer between the memory card and non-volatile device memory.
Example 1:
The parameter backup is to be transferred from the device memory to the memory card with setting 0. The parame-
ter backup is to be stored on the memory card with setting 22.
p0802 = 22 (parameter backup stored on memory card as target with setting 22)
p0803 = 0 (parameter backup stored in device memory as source with setting 0)
p0804 = 2 (start data transfer from device memory to memory card)
--> PS000xxx.ACX is transferred from device memory to memory card and stored as PS022xxx.ACX.
Example 2:
The parameter backup is to be transferred from the memory card to the device memory with setting 22. The param-
eter backup is to be stored in the device memory as setting 0.
p0802 = 22 (parameter backup stored on memory card as source with setting 22)
p0803 = 0 (parameter backup stored in device memory as target with setting 0)
p0804 = 1 (start data transfer from memory card to device memory)
--> PS022xxx.ACX is transferred from memory card to device memory and stored as PS000xxx.ACX.
Example 3 (not supported for PROFIBUS devices):
The communication configuration is to be transferred from the device memory to the memory card.
p0802 = (not relevant)
p0803 = (not relevant)
p0804 = 12 (start data transfer from device memory to memory card)
--> The files that are relevant for the communication configuration are transferred from the device memory to the
memory card and stored in the /SIEMENS/SINAMICS/DATA/CFG directory.
Value: 0:
1:
2:
1001: File on memory card cannot be opened
1002: File in device memory cannot be opened
1003: Memory card not found
1100: File cannot be transferred
Dependency: Refer to: p0802, p0803
Notice: The memory card must not be removed while data is being transferred.
For p0014 = 1, the following applies:
After the value has been modified, no further parameter modifications can be made and the status is shown in
r3996. Modifications can be made again when r3996 = 0.
Note: Once the data has been successfully transferred, this parameter is automatically reset to 0. If an error occurs, the
parameter is set to a value > 1000. Possible fault causes:
p0804 = 1001: The parameter backup set in p0802 as the source on the memory card does not exist or there is not
sufficient memory space available on the memory card.
p0804 = 1002: The parameter backup set in p0803 as the source in the device memory does not exist or there is
not sufficient memory space available in the device memory.
p0804 = 1003: No memory card has been inserted.
If a parameter backup with setting 0 is detected on the memory card when the Control Unit is switched on
(PS000xxx.ACX), this is transferred automatically to the device memory.
When the memory card is inserted, a parameter backup with setting 0 (PS000xxx.ACX) is automatically written to
the memory card when the parameters are saved in a non-volatile memory (e.g. by means of "Copy RAM to ROM").
