F55: Overload Warning Hold Time
Range: 0 - 30sec. (Default: 10sec)
Description: This parameter issues an alarm signal when the current has fallen below the
level in F54-[Overload warning level]. The alarm signal persists for
parameter F55-[Overload warning time] even though the current has
become the level below F54 (see I54, I55). The set value is a percentage of
H33 [Motor rated current, page 92].
Multi-function output terminal (MO-MG) is used as the alarm signal output.
To output the alarm signal, set I54 [Multifunction Output Define, page 119]
to ‘OL’.
z Note: The drive is not tripped by this function, it is only a warning.

•
Select one output terminal for this function between MO and 3AC.
•
If selecting MO as output terminal, set I54 to 5 [Overload:OL].
F56: Overload Trip Select
Range: 0 - 1 (Default: 1)
Description: This parameter turns off the drive output when motor is overloaded.
•
Set F56 to 1.
•
Drive output is turned off when the motor is overloaded.
•
Drive output is turned off when excessive current flows to the motor for
F58 [Overload Trip Time].
F57: Overload Trip Level
Range: 30-200% (Default: 180%)
Description: This parameter sets the amount of overload current. The value is the
percentage of H33- [Motor rated current].
The drive cuts off its output and displays fault message when the output
current persists over the F57 [Overload Trip Level] for the time of F58
[Overload Trip Time]. This function protects drive and motor from
abnormal load conditions.
