Auto current limiting function is used to limit the load current under the preset
current (PD.07) in real time to avoid trip due to over-current. This function is
especially useful for the applications of larger load inertia or sharp change of load.
PD.07 defines the threshold for current limiting. Its setting is a percentage of
drive‘s rated current Ie. PD.08 defines the decreasing rate of output frequency when
the drive is in auto current limiting status. If PD.08 is set too small, overload fault
may occur. If PD.08 is set too big, the drive may be in energy generation status for
long time that may result in overvoltage protection.
The action mode of auto current limiting function is decided by PD.09:
PD.09= 0:
disabled;
PD.09= 1:
auto current limiting is effective during acceleration or
deceleration but ineffective at constant speed;
PD.09= 2:
auto current limiting is effective during
acceleration/deceleration and constant speed;
Pd.10

5
0: disabled;
1~5: times of fault reset;
Pd.11
Auto reset interval
Setting range
：
2
～
20s
When fault occurs, the drive stops output. After the time defined by PD.11, the
drive resets fault automatically and continue running.
PD.10 defines the times of auto fault reset. If PD.10=0, auto reset function is
disabled, and user can only reset fault in manual mode.
