Chapter 7 Fault checking and solution

7.1 Fault alarm and countermeasures

G10 inverter has a total of 30 warning informations and protection functions. In case of
abnormal fault, the protection function will be invoked,the inverter will stop output, and the
faulty relay contact of the inverter will start, and the fault code will be displayed on the
display panel of the inverter. Before consulting the service department, the user can
perform self-check according to the prompts of this chapter, analyze the fault reason and
find out t solution. If you can't solve the fault, please consult the agents of inverter or our
company directly.
During the inverter using process, the following faults may occur. Please conduct simple
fault analysis by referring to the methods below:

Possible Cause
1. Acc/Dec time is too
short.
2. IGBT module fault.
3. Fault caused by
interference.
4. Grounding is not
properly.
1.Acc time is too Short.
2.Motor parameters are
not accurate.
3.The voltage of the grid
is too low.
4.The power of the inverter
129
Solution
1. Increase Acc/Dec time.
2. Ask for support.
3. Inspect external equipment
and eliminate interference.
1.Prolong Acc time.
2.The motor parameters self-
adjusting
3.Check input power.
4.Select inverter with right
