P11.05
Current-limit
selection
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.

P11.06
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 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.
