If F7.07=0, it indicates that the automatic current limiting is invalid when running at a
constant speed;
If F7.07=1, it indicates that the automatic current limiting is valid when running at
constant speed.
During overcurrent and current limiting, the output frequency may change, so on
occasions where a stable output frequency is required when running at a constant speed, it
is better not to use the overcurrent and current limiting function.
When the overcurrent and current limiting is valid, the overload capability of the drive
may be affected due to the low setting of the current limiting level.

When the speed tracking is restarted, select the speed of speed search, the larger the
parameter, the faster the tracking speed. If the setting is too large, the tracking effect is
unreliable. The tracking acceleration shall be adjusted according to the load inertia on site.
When the inertia increases, reduce this value.

The instant stop/nonstop function is used to define whether the drive will automatically
perform low voltage compensation when the voltage drops or instant undervoltage. Reduce
the output frequency appropriately and feed back the energy through the load to maintain
the drive operate without tripping.
F7.14 is set to 0, no action.
F7.14 is set to 1, action (deceleration).
If F7.14 is set to 2, decelerate and stop.
IfF7.14=1, in case of a momentary outrage or a sudden drop in voltage, the drive
decelerates. When the bus voltage returns to normal, the drive will normally accelerate to
the set frequency.
If F7.14=2, the drive will decelerate until it stops when the power is off instantaneously
or the voltage drops suddenly.
