slave during a period of time
Er26-1
SDO index does not
exist
SDO read or write parameters,
the corresponding index does not
exist or is not supported
Check the index and modify EDS
file
Er26-2
SDO sub index does not
exist
SDO read or write parameters,
the corresponding sub index
does not exist or is not supported
Check the index and modify EDS
file
Er26-3
SDO data length error
The length of SDO read or write
command does not match with
the data length in drive object
dictionary.
Adjust the length of SDO R/W
command according to the data
length of drive object dictionary
Er26-4
SDO write data exceeds
the range
The range of SDO write
command exceeds the data
range of drive object dictionary
Adjust written data of SDO
according to the data range in object
dictionary.
Er26-5
Read-only and
non-modifiable
Modify the read-only parameters
Check whether the parameter to be
written is read-only data.
Er26-6
PDO mapping length
error
The mapping length of PDO data
exceed 64 bit
Check the mapping length of PDO
Er26-7
PDO mapping data
does not exist
PDO mapping data cannot be
found in the object dictionary
Check PDO mapping data in the
object dictionary
Er26-8
PDO not allowed to be
changed in the
operating
Modify the PDO mapping during
operation
Switch CANOpen state to
pre-workbench and then modify
PDO mapping
Er26-9
PDO not allow the
mapping
Map the parameters not allowed
into PDO
Check whether there are read-only
PDO parameters being mapped into
RPDO.
Er26-a
Sync signal is too fast
The received frame exceeds the
range allowed by baud rate
1.Modify the interval of data frame
transmission via master station or
the interval of synchronization
frame;
2.Modify communication baud rate.
Er26-b
Receiving fault
CAN communication offline or
the received error exceed 128
1.Check communication wiring;
2.Restart the servo drive.
Er26-c
Transmission fault
CAN communication offline or
received error exceed 128
1.Check communication wiring;
2.Restart the servo drive.
Er26-d
Sync signal repeat
Receive the synchronization
signal of external input when
synchronization signal is from
slave station
Modify the configuration and ensure
only there is only one
synchronization signal generation
source in one communication
network.
