F9 - 06 stall flow point 100%
～
200% [150%]
Over current speed: when the frequency inverter output current reaches the set over current stall protection
current (F9 - 06), the frequency inverter will reduce the output frequency when accelerating operation; Reduce the
output frequency during constant speed operation; During deceleration operation, the speed of descent is slowed
down until the current is less than the over current stall protection current (F9 - 06) before the operating frequency
returns to normal.
Over current stall protection current: select the current protection point with over current speed function. The
frequency inverter starts to perform over-current stall protection function beyond this parameter value. This value is
the percentage of the rated current of the motor.
Over - loss speed gain: used to adjust the frequency inverter's ability to suppress over-current during
acceleration and deceleration. The greater the value, the stronger the ability to suppress over current on the premise
of no over current, and the smaller the gain setting, the better.
For loads with small inertia, the over-loss rate gain should be small; otherwise the system's dynamic response
will slow down.
For loads with large inertia, this value should be large; otherwise, the suppression effect is not good and over
current faults may occur.
When the inertia is very small, it is recommended to set the over current suppression gain to less than 20. The
over-run speed gain is set to 0, the over-run speed function will be cancelled.
F9 - 07 selection of short circuit protection from power
on to ground
0
～
1 [1]
0: power-on short circuit test to ground is invalid.
1: power-on short circuit detection to ground is valid.
This function is valid, and then the uvw end of the frequency inverter will have a voltage output for a period of
time after power - up, which will last for 500 Ms.
F9 - 09 number of automatic resets for faults 0
～
20 [0]
The automatic fault reset function can automatically reset faults in operation according to the set number of
times and interval F9 - 11. When the number of automatic resets is set to 0, automatic resets are prohibited and fault
protection is performed immediately.

Bit: input phase missing protection
0: input phase missing does not fail.
1: the panel displays IPL if the input is out of phase.
10 bits: contactor suction protection
0: contactor failure when not suction.
1: failure when contactor does not suck, panel shows ref
F9 - 13 selection of out-of-phase protection for output 0
～
1 [1]
0: no fault protection when the output is out of phase.
1: when the output is out of phase, fault protection and OPL are displayed on the panel.
