P11.05 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, t
he 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 accelerat
ed 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 low
er
than the current
-limit level again, it will continue
accelerated running.
