2. The actual ACC time for
inertia identifying is too short.
3. The inertia identifying
speed is lower than
150r/min.
3. Increase the setting of P1.06.
Er25-8
Application fault–
Magnetic pole check
failed
1. The power cable phase
sequence is incorrect.
2. The encoder direction
conflicts with the power
cable phase sequence.
3. External force or overload
occurs in the check.
1. Ensure power cable connection
is correct.
2. Ensure encoder settings are
correct.
3. Eliminate the condition that
causes the external force.
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
Check the index on the master node
and on the servo drive. Modify the
index in the EDS file.
