Current
limit
action
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. When the output current is
160.0%
