Load [%]
In this range the characteristic declines dependent on the overcurrent limit
(see unit identification).
On exceeding a load of 105% the overload integrator starts. When falling below the integrator
counts backwards. If the integrator achieves the overload characteristic that corresponds to
the inverter, the error E.OL is triggered.
A.2
Overload protection in the lower speed range

f [Hz]
Min. frequency at continuous full load
(see technical data)
A PT1 element (τ = 280 ms) starts if the permissible current is exceeded. After its sequence of
operation the error E.OL2 is triggered.
