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 transferring the device master data (GSD) to the 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:
12:
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: 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").
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 mem-
ory 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.
