Possible cause
Workaround
Er17-1
Drive overload 2
The short-time load on the
drive is too heavy.
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.
Er18-0
Motor overload
1. Long-term overload
running.
2. Short-time overload.
Replace the drive and motor with
greater power.
Er18-1
Motor overtemperature
The motor temperature is
higher than the temperature
threshold for protection
against overheating.
Replace the motor with greater
power.
Er19-0
Speed fault–Overspeed
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 set
improperly.
3. The setting of P4.32 is
less than that of P4.31.
4. The encoder feedback
signal is interfered.
1. Ensure the electronic gear ratio
is set properly.
2. Ensure the motor speed loop
control parameters are set
properly.
3. Ensure the motor cable phases
are in correct sequence.
4. Ensure the motor and encoder
are connected properly.
5. Replace the motor with a new
one with a higher speed.
Er19-1
Speed fault–CCW
overspeed
The speed feedback
exceeds the setting of P4.40
by more than 20ms.
1. Ensure the encoder is normal.
2. Set P4.40 properly.
Er19-2
Speed fault–CW
overspeed
The speed feedback
exceeds the setting of P4.41
by more than 20ms.
1. Ensure the encoder is normal.
2. Set P4.41 properly.
Er19-3
Speed fault–Overspeed
parameter set incorrectly
The setting of P4.40 is less
than 0 or that of P4.41 is
greater than 0.
1. Ensure the encoder is
connected properly.
2. P4.40 or P4.41 is set
incorrectly.
Er19-4
Overspeed fault–Motor
runaway
The servo motor is out of
control.
1. Ensure the encoder is
connected properly.
2. Ensure the phase sequence of
