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.

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
