Section VI. Fault Diagnosis & Solutions
HV590 is able to make full use of the device performance, while implementing effective
protection. You may encounter following fault tips during operation, please control the following
table analysis the possible causes, and rule out the fault.
6.1 Fault alarm and solutions
HV590 series can not only make full use of equipment performance but also implement
effective protection. HV590 series has 51 alarming information and protection function.Once
fault occurs, protection function acts,output stops, inverter fault relay contact starts,and fault
code is been displayed on the display panel. Before consulting the service department, the user
can perform self-check according to the prompts of this chapter, analyze the fault cause and find
out t solution. If the fault is caused by the reasons as described in the dotted frame, please
consult the agents or our company directly.
Among the 51 items of warning information
：
Fault no.22= Err22refers to hardware over-current or over-voltage signal.In most cases
hardware over-voltage fault led to fault no.22= Err22 alarming.
