The characteristic declines device-dependently in this range (see technical data)
On exceeding a load of 105 % the counter starts. When falling below the counter counts backwards. If the counter
achieves the overload characteristic that corresponds to the inverter the error E.OL is triggered.
2.1.9 Overload protection in the lower speed range
(only valid for F5-M and F5-S, stall current see technical data)
OC-tripping current
Short-time limit current
Start of overload
integrator at 105%
Stall current
If the permissible current is exceeded a PT1-element (τ =280ms) starts, after its sequence of operation the error E.OL2 is
triggered.
