large, the actual acceleration rate of motor is lower
than that of output frequency, if no measures are
taken, the inverter may trip due to overcurrent
during acceleration.

Automatic
current-limit level
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 inverter 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 inverter 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.
