DC bus voltage V
If the bus voltage exceeds the overvoltage
stalling point, the motor is in power generation
state, and the overvoltage stalling protection
function takes effect to regulate output
frequency (that is, consume unnecessary
regenerative electricity).

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.

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 accelerated running,
or run in decreased frequency during
constant-speed running; if it exceeds the
current-limit level continuously, the VFD output
