11.2 SDO Error codes
In the case of an error (SDO response CCS = 0x80) the data field contains a 4-byte
error code. By the measuring system the following error codes are supported:
Error code Meaning
0x0503 0000
0x0504 0001
0x0601 0000
0x0601 0001
0x0601 0002
0x0602 0000
0x0604 0041
0x0604 0042
0x0607 0010
0x0609 0011
0x0609 0030
0x0800 0020
0x0800 0022
0x0800 0024

Remedy
- General bus load ≤ 85 % !
- Attempt to increase the baud rate
- Increase cycle time for node guarding
- Try to restart the device: Voltage OFF/ON.
If this measure does not help, the device must be
replaced.
Command codes supported by the device see SDO
message format on page 110.
Check which attribute for the corresponding object
is valid:
- rw: read- and write access
- wo: write only access
- ro: read only access
- Const: read only access
Overview of the objects see Table 10 and Table 12
on page 151 and 165.
Write command codes supported by the device
see SDO message format on page 110.
Read command codes supported by the device
see SDO message format on page 110.
Objects supported by the device see pages 151,
161 and 165.
PDO mapping objects supported by the device
see pages 171 and 172.
Check
- Mapping objects ≤ 8 byte data length per TPDO
- Number of mapping objects ≤ 3 per TPDO
Number of bytes of the command code must match
to the type of object, see also page 110.
Check which sub-indices the corresponding object
supports.
Check
permissible
range
corresponding object.
Wrong signature written when storing/restoring the
parameters,
see objects 1010h/1011h, page 156/157.
Wrong procedure for the mapping configuration
performed, see Procedure for re-mapping on page
149.
Indication that no more errors are present at read
access to object 1003h sub-index 01, see page 153.
