F5 Group: Fault and Protection
F5-00
Motor overload protection selection
Default
1
Setting
range
0: Disabled
1: Enabled
0: The inverter has no overload protection for the motor
and the thermal relay shall be installed;
1: the inverter has motor overload protection function
and the protection value is shown in F5-01.
F5-01
Motor overload protection coefficient
Default
1
Setting
range
0.20~ 10.00
This value is the ratio of motor over temperature action
point to motor rated current, if the output current is larger
than F5-01×motor rated current, it will enter into the
inverse time-lag protection status. The inverter will alarm
that the motor is overloaded after 60 minutes has passed
if the output current is equal to 150%×F5-01×motor rated
current.
F5-02
Overvoltage stall gain
Default 0
Setting
range
0 (no overvoltage
stall) ~ 100
Adjust the overvoltage stall capacity of the inverter to avoid
overvoltage fault. The bigger is the value, the more powerful
the suppressing capacity is.
For the load with small inertia, the small value is
recommended, or it will slow down the system adjustment.
For the load with large inertia, the big value is
recommended; otherwise there will be a poor suppressing
effect.
F5-03
Overvoltage stall action value
Default 130.0%
Setting range 120% ~ 150%
Select the protection value of the overvoltage stall
function. The inverter starts executing the voltage stall
protection function when this value is surpassed.
F5-04
Overcurrent stall gain
Default 60
Setting
range
0 ~ 200
Adjust the overcurrent stall capacity of the inverter to
avoid overcurrent fault. The bigger is the value, the more
powerful the suppressing capacity is.
For the load with small inertia, the small value is
recommended, or it will slow down the system
adjustment.
For the load with large inertia, the big value is
recommended; otherwise there will be a poor
suppressing effect.
F5-05
Overcurrent stall action value
Default 150.0%
