Setting Range Parameter Description
F9-66
Threshold of power dip
ride-through function
enabled
80% 60% to 100%
Used to set the voltage level at which the
bus voltage is maintained upon power loss.
When a power loss occurs, the bus voltage is
retained at a value around F9-66 (Threshold
of power dip ride-through function enabled).
F9-75
Power dip ride-through
gain
0 to 100 40
This parameter is valid only in bus voltage
constant control (F9-59 = 1).
If undervoltage occurs frequently during
power dip ride-through, increase the power
dip ride-through gain and coefficient.
F9-76
Power dip ride-through
integral
0 to +100 30
F9-77
Deceleration time of
power dip ride-through
0 to 300.0s 20.0s
This parameter is valid only for the
decelerate to stop mode (F9-59 = 2).
When the bus voltage is lower than the value
of F9-62, the AC drive decelerates to stop.
The deceleration time is determined by this
parameter instead of F0-18.
4.6.9 Fault Reset
AC drive hardware fault (E01), EEPROM fault (E21), short-circuit to ground fault (E23), and STO-BUFFER
fault (E47.05) cannot be reset automatically or manually. They can only be reset after power down. The
fault protection action is performed after the fault auto reset times is reached.

F9-09
Fault auto reset times
0 0 to 20
Used to set the fault auto reset times of the
AC drive when automatic fault reset is
selected for the AC drive. If the reset times
exceed the value of this parameter, the AC
drive will remain in the faulty state.
F9-10
DO action during auto
fault reset
1 0: Not act
1: Act
Used to decide whether the DO (assigned
with function 3) acts during the fault auto
reset if the fault auto reset function is
selected.
F9-11
Auto fault reset interval
1.0s 0.1s to 100.0s
Used to set the delay of auto reset after the
AC drive reports a fault.
4.6.10 Fault Protection Action Selection
The faults of this product are divided into five grades, and the serious grades of faults from high to low
are: coast to stop, decelerate to stop, restart upon fault, alarm, and fault cancellation.
When alarm is selected as the fault protection action, the operating panel displays Axx.xx, such as
"A16.02".
When cancellation is selected as the fault protection action, no prompt will be displayed when the
corresponding fault occurs, so be careful when using this setting.
