Chapter 4 - Parameter Description [FU1]

FU1-54: Overload Warning Level
FU1-55: Overload Warning Time
The inverter generates an alarm signal when the
output current has reached the FU1-54 [Overload
Warning Level] for the FU1-55 [Overload Warning
Time]. The alarm signal persists for the FU1-55
even if the current has become the level below
the FU1-54.
Multi-function output terminal (MO-MG) is used as
the alarm signal output. To output the alarm signal,
set I/O 44 [Multifunction Output] to ‘OL’.
☞
Note: Inverter is not tripped by this function.
☞ Note: The set value is the percentage of FU2-33 [Rated Motor
Current].
[Overload Warning]
FU1-56: Overload Trip Selection
FU1-57: Overload Trip Level
FU1-58: Overload Trip Delay Time
Inverter cuts off its output and displays fault
message when the output current persists over
the FU1-57 [Overload Trip Level] for the time of
FU1-58 [Overload Trip Time]. This function
protects the inverter and motor from abnormal
load conditions.

Note: The set value is the percentage of FU2-33 [Rated Motor
Current].
