FU1-66: Overload Trip Selection
FU1-67: Overload Trip Level
FU1-68: Overload Trip Delay Time
Inverter cuts off its output and displays fault message
when the output current persists over the FU1-67
[Overload Trip Level] for the time of FU1-68
[Overload Trip Time]. This function protects the
inverter and motor from abnormal load conditions.
Note: The set value is the percentage of FU2-43
[Rated Motor Current].
Note: Activated only when Heatsink temperature
exceeds its preset level.

FU1-71: Stall Prevention Level
This bit set parameter follows the conventions used
in I/O-15 and I/O-16 to show the ON (bit set) status.
This function is used to prevent the motor from
stalling by reducing the inverter output frequency
until the motor current decreases below the stall
prevention level. This function can be selected for
each mode of acceleration, steady speed, and
deceleration via bit combination.
