UV Bus undervoltage

The voltage of the power
supply is too low.

Check the input power of
the supply line.
OL1 Motor overload

The voltage of the power
supply is too low;

The motor setting rated
current is incorrect;

The motor stall or load
transients is too strong.

Check the power of the
supply line;

Reset the rated current of
the motor;

Check the load and
adjust the torque lift.
OL2 VFD overload

The acceleration is too
fast;

Reset the rotating motor;

The voltage of the power
supply is too low;

The load is too heavy;

The motor power is too
large, and the power of
the VFD is too small.

Increase the ACC time;

Avoid the restarting after
stopping;

Check the power of the
supply line;

Select a VFD with bigger
power;

Select a proper motor.
SPI
Phase loss on
input side

Phase loss or violent
fluctuation occurred to R,
S, and T input.

Check input power;

Check installation
distribution.
SPO
Phase loss on
output side

Phase loss occurred to
U, V, W output (or the
three phases of motor is
asymmetrical)

Check the output
distribution;
