Er25-9
Application fault–
Overtravel/overspeed in
confirmation of magnetic
pole check
The motor motion range is
too large or speed is too fast
in the confirmation of
magnetic pole.
Increase the setting of P6.70.
Er25-a
Application fault–Out-of-
range in magnetic pole
check
The motor motion range
exceeds the specified range
in the magnetic pole check.
Increase the settings of P6.60
and P6.61.

Er22-3
Synchronization
signal timeout
In
Interpolation
position
mode, the time interval
between
two
adjacent
synchronization
frame
signals is more than twice
the communication cycle.
1.
Check communication cables to
improve communication reliability.
2. Ensure
the synchronization frame
generation interval of the signal
generation source is correct.
Er22-4
Full position
command buffer
CANopen
PTP
position
command buffer is full.
Increase the time interval for
sending
PTP
control
position
commands.
Er26-0
CANopen offline
The master node does not
receive heartbeat packets
from a slave node within a
period of time.
Check communication connection.
Er26-1
SDO index not exist
When the SDO reads or
writes parameters, the index
does not exist in the object
dictionary or is not supported
by the servo drive.
Check the index on the master node
and on the servo drive. Modify the
index in the EDS file.
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
Adjust the length in SDO read or
write commands according to the
