Possible cause
transients

Acceleration is too fast.

The motor is restarted
during rotating.

The grid voltage is too low.

The load is too large.

Phase loss or fluctuation
occurs to input R, S and T.

Phase loss output occurs
to U, V and W (or serious
3PH imbalance occurs to
the load).

Air duct blocked or fan
damaged.

Ambient temperature is too
high.

Long-time overload
running.

S external fault input
terminal acts.

Baud rate is set improperly.

Communication line fault.

Communication address
error.

Communication suffers
strong interference.

Poor contact of controller
board connector.

Hall components are
damaged.

Amplifying circuit is
abnormal.

