The following diagram shows the switch-off time for an inverter with overload char-
acteristics depending on the constant load:
Figure 6: Overload characteristic
The overload characteristic valid for the respective inverter can be found in the in-
stallation manual for the power unit.
The drive switches off automatically on reaching the overload limit (ru29 OL coun-
ter = 100%).
The error reaction can be programmed as described above via the object pn04
E.OL stop mode . A warning level can be programmed additionally.
On reaching this "OL-Counter“ value bit 0 is set in the warning state and with ap-
propriate adjustment of the warning mask also bit 7 is set in the status word.
The error or warning can be reset when the OL counter has reached the value of *
pn03 OL warning level / 2.
