UV
DC bus Under-voltage
The voltage of the power supply
is too low.
Check the input power of the
supply line
OL1
Motor overload
1. The voltage of the power
supply
is
too
low.
2. The motor setting rated
current
is
incorrect.
3. The motor stall or load
transients is too strong.
1. Check the power of the
supply
line
2. Reset the rated current of the
motor
3. Check the load and adjust the
torque lift
OL2
Inverter overload
1. The acceleration is too fast
2. Reset the rotating motor
3. The voltage of the power
supply
is
too
low.
4. The load is too heavy.
5. Close loop vector control,
reverse direction of the code
panel
and
long
low-speed
operation
1. Increase the ACC time
2. Avoid the restarting after
stopping.
3. Check the power of the
supply
line
4. Select an inverter with bigger
power.
5. Select a proper motor.
OL3
Electrical overload
The inverter will report overload
pre-alarm according to the set
value.
Check the load and the overload
pre-alarm point.
SPI
Input phase loss
Phase loss or fluctuation of
input R,S,T
1. Check input power
2. Check installation distribution
SPO
Output phase loss
U,V,W
phase
loss
input(or
serious
asymmetrical
three
phase of the load)
1. Check the output distribution
2. Check the motor and cable
