control is valid (F07.11=1) during operation, the current limit function of the inverter will
be enabled. The output frequency will be reduced to limit the increase in output current,
thus disabling the overcurrent stall of the inverter. When the output current decreases to
below the current limit level, the original running status will be restored. The current limit
process is shown in Fig. 7-24.
Fig. 7-24 Current Limit Process
F07.12 is used to set the operating conditions of current limit. If the current of the
inverter is greater than the set value of this code, the current limit function will be enabled,
thus controlling the output current not to exceed the current limit level.
The current limit is valid only for the V/F drive mode. It is recommended to use
this function in the case of large inertia or fan type loads or driving of multiple
motors by a single inverter.
