Code
Name
Possible cause
Workaround
Er22-2
Position increment
overflow
The single-variation position
command after electronic
gear
ratio
conversion
exceeds (2
31
-1).
1. Decrease the single variation
of the position command.
2. Modify the electronic gear ratio
to a proper setting.
Er23-0
Drive overtemperature
1. The ambient temperature
of the drive exceeds the
specified temperature.
2. The drive is overloaded.
1.
Reduce
the
ambient
temperature and improve the
ventilation condition.
2. Replace it with a servo system
with greater power.
3. Increase the ACC/DEC time
and reduce the load.
Er25-4
Application fault–
Encoder offset angle test
timeout
An exception occurred in the
encoder offset angle test.
Ensure the motor shaft can rotate
freely and then carry out the test
after repower-on.
Er25-5
Application fault–
Encoder offset angle test
failed
There is great fluctuation in
current feedback in the
encoder offset angle test.
Reduce the setting of P4.53 and
then carry out the test after
repower-on.
Er25-6
Application fault–Homing
offside
The limit switch or software
limit is enabled during
homing.
Modify the setting of P5.10 and
then execute homing after
repower-on.
Er25-7
Application fault–Inertia
identifying failed
1. During inertia identifying,
the motor stops rotating with
vibration of longer than 3.5s.
2. The actual ACC time for
inertia identifying is too
short.
3. The inertia identifying
speed
is
lower
than
150r/min.
1. Improve the mechanical
rigidity properly.
2. Increase the setting of P1.07.
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.
