Learning Protection Features
When the current supplied to the motor is greater than the
value set in the overload trip level (OL Trip Level) and
continues for the overload trip time (OL Trip Time), the
inverter output is either blocked or decelerates according
to the Pr.20 selection.
Set to 1 (Yes) to activate the overload warning function. If 0 (No)
is selected, the function is disabled.
When the current to the motor is greater than the overload
warning level (OL Warn Level) and continues at that level for the
overload warning time (OL Warn Time), the multi-function
(digital) output (Relay 1 or Relay 2) sends a warning signal.
Multi-function (digital) relay outputs a signal if OU.31 or OU.33
are set to 5 (Over load). The inverter does not trip when
warning levels are reached.
The overload warning signal will not work if the overload warn level (OL Warn Level) and the overload
warn time (OL Warn Time) are set higher than the overload trip level (OL Trip Level) and overload trip
time (OL Trip Time).
