Workaround
dictionary or is not supported
by the servo drive.
Er26-2
SDO sub-index not
exist
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.
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.
Er26-3
Incorrect SDO data
length
The length information in
SDO read or write
commands does not match
the data length in the servo
drive object dictionary.
Adjust the length in SDO read or
write commands according to the
data length in the servo drive object
dictionary.
Er26-4
SDO data out of range
The data that the SDO writes
exceeds the data range in
the servo drive object
dictionary.
Adjust the size of data written by the
SDO according to the data range in
the object dictionary.
Er26-5
Modification not
allowed for read-only
There are attempts to modify
read-only parameters.
Eliminate the condition for making
the attempts to modify read-only
parameters.
Er26-6
Incorrect PDO
mapping length
The total length of data
mapped from the PDO
exceeds 64 bits.
Correct the length settings.
Er26-7
PDO mapping data
not exist
The parameters associated
with the data mapped from
the PDO are not found in the
object dictionary.
Ensure the PDO mapping index and
sub-index exist in the object
dictionary.
Er26-8
PDO modification not
allowed in operational
state
There are attempts to modify
PDO mappings.
Switch the CANopen status machine
to pre-operational and then modify
PDO mappings.
Er26-9
PDO mapping not
allowed
There are attempts to map
parameters that disallow
mapping to the PDO.
Ensure there are no read-only PDO
parameters that are mapped to the
RPDO.
Er26-a
Synchronization signal
too fast
In synchronization working
mode, the number of frames
received by a slave node
exceeds the range supported
1. Modify the time interval for the
master node to send data or
synchronization frames.
2. Change the baud rate.
