The overcurrent and current limiting function is to limit it not exceeding the set
automatic current limiting level (F7.06), through the real-time control of the load current, to
prevent fault trips caused by current overshoot. For load occasions with large inertia or
intense changes, this function is especially suitable.
The overcurrent and current limiting level (F7.06) defines the current threshold of the
overcurrent and current limiting action, and its setting range is relative to the percentage of
the drive rated current. G type drive factory value is 150%, and P type drive factory value is
110%. If this parameter is exceeded, the drive starts executing protection function of
overcurrent stall.
Overcurrent stall gain (F7.08) is used to adjust the drive's ability to suppress
overcurrent during acceleration/deceleration. The larger this value, the stronger the ability
to suppress overcurrent. Under the premise of no overcurrent, the smaller the set gain, the
better. When the overcurrent gain is set to 0, the overcurrent stall function is invalid.
The overcurrent and current limiting function is always effective under the
acceleration/deceleration status. Whether the overcurrent and current limiting function is
effective during constant speed operation is determined by the overcurrent and current
limiting action selection (F7.07).
