120–150% (standard bus voltage) (220V)
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
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 accelerated running.
