If the permissible current is exceeded a PT1-element (τ=280ms) starts, after its sequence of operation
the error E.OL2 is triggered.

The characteristic declines device-dependently in this range (see rating plate)
On exceeding a load of 105% the overload timer starts. When falling below the timer counts backwards.
If the timer achieves value for the overload characteristic that corresponds to the inverter, the error E.OL
is triggered.
