During operation, if output current reaches to current limit level F07.12 and current
limit control is effective (F07.11=1), then the system will automatically start current limit:
reducing output frequency to restrain the output current from going up, and inverter will
quit from over current state. Inverter will return to previous running status, when output
current reduces to a value below current limit action level. Current limit action procedure
is shown in Figure 7-25.

F07.12 is used to set the action conditions for enabling current limit. If inverter
output current exceeds the set value of this function code, current limit function starts to
