Overload Early Warning and Trip Setting Details
Used in underloads, like fans and pumps (overload
tolerance: 120% of rated underload current for 1
minute). IP66 models do not support normal duty
operation.
Used in heavy loads, like hoists, cranes, and parking
devices (overload tolerance: 150% of rated heavy
load current for 1 minute).
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.
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, Q1)
sends a warning signal. When Over Load is selected at OU.31 and 33, the
multi-function output terminal or relay outputs a signal. The the signal
output does not block the inverter output.
Select the inverter protective action in the event of an overload fault trip.
No protective action is taken.
In the event of an overload fault, inverter output is
blocked and the motor will free-run due to inertia.
If a fault trip occurs, the motor decelerates and stops.
When the current supplied to the motor is greater than the preset value at
the overload trip level (OL Trip Level) and continues to be supplied during
