7.2 Common Faults and Solutions

Inverter may have following faults or malfunctions during operation, please refer to the
following solutions.

No display after power on:

z

Inspect whether the voltage of power supply is the same as the inverter rated
voltage or not with multi-meter. If the power supply has problem, inspect and solve
it.

z

Inspect whether the three-phase rectify bridge is in good condition or not. If the
rectification bridge is burst out, ask for support.

z

Check the CHARGE light. If the light is off, the fault is mainly in the rectify bridge or
the buffer resistor. If the light is on, the fault may be lies in the switching power
supply. Please ask for support.

Power supply air switch trips off when power on:

z

Inspect whether the input power supply is grounded or short circuit. Please solve
the problem.

z

Inspect whether the rectify bridge has been burnt or not. If it is damaged, ask for
support.

Motor doesn’t move after inverter running:

z

Inspect if there is balanced three-phase output among U, V, W. If yes, then motor
could be damaged, or mechanically locked. Please solve it.

z

If the output is unbalanced or lost, the inverter drive board or the output module
may be damaged, ask for support..

Inverter displays normally when power on, but switch at the input side trips when
running:

z

Inspect whether the output side of inverter is short circuit. If yes, ask for support.

z

Inspect whether ground fault exists. If yes, solve it.

z

If trip happens occasionally and the distance between motor and inverter is too far,
it is recommended to install output AC reactor.
