Possible cause
The short-time load on the
drive is too heavy.
1. Long-term overload
running.
2. Short-time overload.
The motor temperature is
higher than the temperature
threshold for protection
against overheating.
The motor speed absolute
value exceeds the setting of
P4.32.
1. The motor stalls or motor
phases U, V, and W are in
reverse sequence.
2. The electronic gear ratio
or motor speed loop control
parameters are
improperly.
3. The setting of P4.32 is
less than that of P4.31.
4. The encoder feedback
signal is interfered.
The speed feedback
exceeds the setting of P4.40
by more than 20ms.
The speed feedback
exceeds the setting of P4.41
by more than 20ms.
The setting of P4.40 is less
than 0 or that of P4.41 is
greater than 0.
The servo motor is out of
control.

Workaround
1. Reduce the load.
2. Ensure there is no phase
dislocation or phase loss to the
UVW wiring of the motor and the
encoder is correct.
3. Ensure the motor matches the
drive.
Replace the drive and motor with
greater power.
Replace the motor with greater
power.
1. Ensure the electronic gear ratio
is set properly.
2. Ensure the motor speed loop
control parameters
properly.
3. Ensure the motor cable phases
are in correct sequence.
set
4. Ensure the motor and encoder
are connected properly.
5. Replace the motor with a new
one with a higher speed.
1. Ensure the encoder is normal.
2. Set P4.40 properly.
1. Ensure the encoder is normal.
2. Set P4.41 properly.
1. Ensure the

2. P4.40 or
incorrectly.
1. Ensure the
connected properly.
2. Ensure the phase sequence of
