Description
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
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.

Setting range of P11.06: 50.0–250.0%
Setting range of P11.07: 0.00–50.00Hz/s
If the VFD or motor output current is larger than
the overload pre-alarm detection level (P11.09),
and the duration exceeds the overload pre-alarm
detection time (P11.10), overload pre-alarm signal
will be outputted.
