Current limit
mode
During accelerated running, as the load is
too large, the actual acceleration rate of
motor is lower than that of output frequency,
if no measures are taken, the VFD may trip
due to overcurrent during acceleration.

P11.06
Automatic
current limit
threshold
Current-limit protection function detects
output current during running, and compares
it with the current-limit level defined by
P11.06 , if it exceeds the current-limit level,
the VFD will run at stable frequency during
accelerated running, or run in decreased
frequency during constant-speed running; if
it exceeds the current-limit level
continuously, the VFD output frequency will
drop continuously until reaching lower limit
frequency. When the output current is
detected to be lower than the current-limit
level again, it will continue accelerated
running.
