Overload Characteristic
If the load current exceeds the rated current but is below the over current level, an
overload timer begins counting. The rate at which the timer increments is a function
of load current. The higher the current the faster the increments. When the counter
reaches the limit the fault E.OL is triggered and the output to the motor is shut off.
At this point the inverter begins a cool down period where the inverter is allowed to
cool before the fault can be reset.
The overload curves are
dependent on the invert-
er housing size.
