Possible cause
dictionary or is not supported
by the servo drive.
When the SDO reads or
writes parameters, the index
exists in the object dictionary,
but the sub-index does not
exist in the dictionary or is
not supported by the servo
drive.
The length information in
SDO read or
commands does not match
the data length in the servo
drive object dictionary.
The data that the SDO writes
exceeds the data range in
the servo drive
dictionary.
There are attempts to modify
read-only parameters.
The total length of data
mapped from the
exceeds 64 bits.
The parameters associated
with the data mapped from
the PDO are not found in the
object dictionary.
There are attempts to modify
PDO mappings.
There are attempts to map
parameters that
mapping to the PDO.
In synchronization working
mode, the number of frames
received by a slave node
exceeds the range supported
-270-
Check the index and sub-index on
the master node and on the servo
drive. Modify the index and sub-index
in the EDS file.
Adjust the length in SDO read or
write
write commands according to the
data length in the servo drive object
dictionary.
Adjust the size of data written by the
SDO according to the data range in
object
the object dictionary.
Eliminate the condition for making
the attempts to modify read-only
parameters.
PDO Correct the length settings.
Ensure the PDO mapping index and
sub-index
dictionary.
Switch the CANopen status machine
to pre-operational and then modify
PDO mappings.
Ensure there are no read-only PDO
disallow parameters that are mapped to the
RPDO.
1. Modify the time interval for the
master node to
synchronization frames.
2. Change the baud rate.
