9.2.6 SDO protocol
[ 1 ] About SDO
The SDO (Service Data Object) protocol is used to set and adjust the inverter. SDO enables to access all objects
(parameters) of the inverter. The CANopen communication of inverter supports a single Server SDO.
For information about how to transmit data in SDO, refer to the manual of the master or configuration tool.
For information about the objects, refer to “9.2.8 Object list”.
[ 2 ] Response on SDO error
If the access in SDO has an error, this communication card returns an Abort code listed in Table 9.2-13.
Table 9.2-13 Abort Codes on SDO Access Error
Abort codes Description
0503 0000 Error on divided SDO transmission: Improper toggle bit
0504 0000 Response timeout error
0601 0000 Unsupported access to an object
0601 0001 Write only object is read
0601 0002 Read only object is written
0602 0000 Parameter does not exist
0604 0041 Object cannot be mapped to the PDO.
0604 0042 The number and length of the objects to be mapped would exceed PDO length.
0606 0000 Writing while EEPROM is running of inverter
0607 0010 Different parameter’s data type
0607 0012 Data type does not match, length of service parameter too high.
0607 0013 Data type does not match, length of service parameter too low.
0609 0011 Accessed to the object without subindex
0609 0030 The value written is out of range
0609 0031 Value of parameter written too high.
0609 0032 Value of parameter written too low.
0800 0021
Inverter function code write error
(SO1, SO5, and SO6 are written by CANopen when the link to RS-485 communication port is valid)
0800 0022 Write to inverter function code is disabled (running, writing, digital input terminal is ON)
