Turn-off time t depending on the overload I/IN at OC level 180%
• On exceeding a load of 105 % the overload integrator starts.
• When falling below the integrator counts backwards.
• If the integrator reaches the overload characteristic „Error! overload (OL)“ is trig-
gered.
After a cooling down period, the integrator can be reset now. The drive converter must
remain switched on during the cooling down phase.
Operation in the range of the thermal overload limit
Due to the high steepness of the overload characteristic, the duration of a permissible
overload in this range
①
cannot be determined exactly. Therefore, the design of the drive
converter should be assumed to have a maximum overload time of 300s.
