1. The overcurrent stall function is to
automatically limit the overcurrent stall
level (F7.04) not exceeding the setting,
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.
2. The overcurrent stall level (F7.04)
defines the current threshold of the
overcurrent stall action, and its setting
range is relative to the percentage of the
drive rated current. When this parameter
value is exceeded, the drive starts to
implement the overcurrent stall protection
function.
3. Overcurrent stall gain, and
overcurrentstall integration time: Used to
adjust the drive's ability to suppress
overcurrent during acceleration and
deceleration. The larger the gain, and the
longer the integration time, the stronger
the ability to suppress overcurrent, and
the drive's acceleration/deceleration time
becomes longer accordingly. So, under
the premise of no overcurrent, the smaller
the gain and the longer the integration
time, the better the effect.
4. The overcurrent stall function is always
effective under the
acceleration/deceleration status. Whether
the overcurrent stall function is effective
during constant speed operation is
determined by the overcurrent stall action
selection (F7.05).
F7.05
＝
0 overcurrent stall is invalid
during constant speed operation;
F7.05
＝
1 overcurrent stall is valid during
constant speed operation.
