Overload Early Warning and Trip Setting Details
Code Description
PRT-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.
PRT-18
OL Warn Level,
PRT-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, Q1)
sends a warning signal. When Over Load is selected at OUT-31, OUT-33,
the multi-function output terminal or relay outputs a signal. The signal
output does not block the inverter output.
PRT-20
OL Trip Select
Select the inverter protective action in the event of an overload fault trip.
Setting Function
0 None No protective action is taken.
1 Free-Run In the event of an overload fault, inverter output is
blocked and the motor will free-run due to inertia.
3 Dec If a fault trip occurs, the motor decelerates and stops.
PRT-21 OL Trip
Level,
PRT-22 OL Trip
Time
When the current supplied to the motor is greater than the preset value of
the overload trip level (OL Trip Level) and continues to be supplied during
the overload trip time (OL Trip Time), the inverter output is either blocked
according to the preset mode from PRT-17 or slows to a stop after
deceleration.
