stalling.
3. Pulse input frequency is
too high, exceeding the
maximum motor speed.
4. The step variable in the
position command input
exceeds the setting of P4.33.
position loop or speed
feed-forward gain parameters.
Alternatively, increase the setting
of P4.33.
3. Adjust electronic gear ratio
parameters.
4. Reduce the step variable in the
position command input.
Er22-1
Hybrid control deviation
too large
In fully-closed loop control,
the feedback position
deviation between the
grating ruler and encoder
exceeds the setting of P4.64.
1. Ensure the motor and load are
connected properly.
2. Ensure the grating ruler and
encoder are connected properly.
3. Ensure P4.60, P4.61, and
P4.62 are set properly.
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.
1. Improve the mechanical rigidity
properly.
2. Increase the setting of P1.07.
