6.1.2 Overload Early Warning and Trip
A warning or fault ‘trip’ (cutoff) occurs when the motor reaches an overload state,
based on the
motor’s rated current. The amount of current for warnings and trips can
be set separately.

Pr.04 Load Duty
Select the load level.
Configuration Function
0
Normal
Duty
Used in underloads, like fans and pumps
(overload tolerance: 120% of rated underload
current for 1 minute).
1
Heavy
Duty
Used in heavy loads, like hoists, cranes, and
parking devices (overload tolerance: 150% of
rated heavy load current for 1 minute).
Pr.17 OL Warn
Select
If the overload reaches the warning level, the terminal block multi-
function output terminal and relay are used to output a warning
signal. If 1 (Yes) is selected, it will operate. If 0 (No) is selected, it
will not operate.

Level,
Pr.19 OL Warn
Time
When the input current to the motor is greater than the overload
warning level (OL Warn Level) and continues at that level during the
overload warning time (OL Warn Time), the multi-function output
(Relay 1, Relay 2) sends a warning signal. Multi-function relay
terminal and relay outputs signal if OU.31 and OU.33 codes are set
to 5 (Over load). The signal output does not block the inverter
output.
