9.2 CANopen communication faults and workarounds

Code Name
Synchronization signal
Er22-3
timeout
Full position command
Er22-4
buffer
Er26-0 CANopen offline
Er26-1 SDO index not exist
Possible cause
2. The actual ACC time for
inertia identifying is too short.
3. The inertia identifying
speed is lower
150r/min.
1. The power cable phase
sequence is incorrect.
2. The encoder direction
conflicts with
cable phase sequence.
3. External force or overload
occurs in the check.
The motor motion range is
too large or speed is too fast
in the confirmation
magnetic pole.
The motor motion range
exceeds the specified range
in the magnetic pole check.
Possible cause
In Interpolation
mode, the time
between two
synchronization
signals is more than twice the
communication cycle.
CANopen PTP
command buffer is full.
The master node does not
receive heartbeat packets
from a slave node within a
period of time.
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
