Automatic current limiting protection function in the process of inverter operation is
comparing with the current limit levels is determined by Fb.10 through detecting the
output current.When more than current limit levels,the inverter output frequency will be
carried out in accordance with the flow frequency decrease rate of decline;When the level
of output current is lower than the current limit point again,the inverter will recover to the
normal operation.As shown in figure:
Fig.6-29 Current limiting protection function
During auto current limiting process, the inverter's output frequency may change;
therefore, it is recommended not to enable the function when inverter needs to output
stable frequency.
During auto current limiting process, if Fb.10 is too low, the overload capacity will be
impacted.
