When fault occurs, the function code and its contents will be shown in LED display, the protection function starts, the inverter
stops outputting and the fault relay contact point is activated.Before seeking services, the subscriber may conduct the self-
check according to the prompt given in this section, analyze the fault causes, and find out the solutions.If the fault belongs to
the causes described in the broken line box, please seek the service by contacting the inverter agent or directly contacting our
corporationl.

E-01
Over-current
during
acceleration
Too heavy the load and too short the Acc time Prolong the Acc time
V/F curve is not suitable Adjust V/F curve
The rotating motor restarts after stop Set as “start on fly” function
Too large the value of torque boost
Adjust the value of manual torque boost or change it as
auto torque
