less than the power supply
voltage).
3. Wrong cable phase
sequence, loose power
cable, cable damage or
open circuit (fault recording
characteristics: the output
current is zero, and the
output voltage is close to the
power supply voltage).
4. Motor phase loss or three-
phase imbalance.
5. Due to unreasonable gain
parameter
setting,
the
system
vibrates
which
usually occurs in the flexible
drive industry.
6. With the multi-shaft
system, the encoder and the
power cables are cross-
connected
to
different
shafts.
7. Hardware of the drive is
damaged.
terminal and aviation plug are
tightened.
4. Three phases inside the motor
are imbalanced. Replace the
servo motor;
5. Reduce the gain;
6. Ensure the multi-shaft cables
are not cross-connected. If it
occurs, it is necessary to correct
it.
7. Replace the servo drive.

Motor overtemperature
The motor temperature is
higher than the temperature
threshold
for
protection
against overheating.
Replace the motor with greater
power.

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.
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.
