dictionary.
Er26-4
SDOCANopen fault–
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 by the baud rate.
1. Modify the time interval for the
master node to send data or
synchronization frames.
2. Change the baud rate.
Er26-b
Receiving fault
CAN communication is
offline or the error receiving
counter exceeds 128.
1. Check communication
connection.
2. Restart the servo drive.
Er26-c
Sending fault
CAN communication is
offline or the error receiving
counter exceeds 128.
1. Check communication
connection.
2. Restart the servo drive.
Er26-d
Duplicate
synchronization
signal
In the case where a slave
node is configured to
generate synchronization
signals, external
Modify configuration so that there is
only one synchronization signal
generation source in the entire
communication network.
