F52 [Electronic
thermal level
for continuous]
50/150
[%]
This parameter sets the amount of
current to keep the motor running
continuously.
It cannot be set higher than F51 –
[Electronic thermal level for 1 minute].
100 0
0 Standard motor having cooling fan
directly connected to the shaft
F53 [Motor cooling
method]
0/1
1 A motor using a separate motor to
power a cooling fan.

F54 [Overload
warning level]
30/150
[%]
This parameter sets the amount of
current to issue an alarm signal at a relay or
multi-function output terminal (see I54, I55).
The set value is the percentage of H33-
[Motor rated current].
150 0
F55 [Overload
warning time]
0/30 [sec] This parameter issues an alarm signal
when the current greater than F54-
[Overload warning level] flows to the motor
for F55- [Overload warning time].

F56 [Overload trip
select]
0/1 This parameter turns off the inverter
output when motor is overloaded.
1 0
F57 [Overload trip
level]
30/200
[%]
This parameter sets the amount of
overload current.
The value is the percentage of H33-
[Motor rated current].
180 0
F58 [Overload trip
time]
0/60 [sec] This parameter turns off the inverter
output when the F57- [Overload trip level] of
current flows to the motor for F58- [Overload
trip time].
