Figure 2: Overload characteristic
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 drive converter, „ERROR overload“ is triggered
After a cooling period the message „no ERROR overload“ is displayed. The error can
be reset now. The drive converter must remain switched on during the cooling period.
