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 inverter may trip due to
overcurrent during acceleration.

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
