3.2.3.1 Overload characteristic (OL) for 230 V devices
All drive converters with overload characteristic of 180 % or 216 % can be operated at
rated switching frequency with an utilization of 150 % for 60 s.
Restrictions:
• The thermal design of the heat sink is based on the rated operation. The following
values are taken into account: Rated output current, ambient temperature, rated
switching frequency, rated voltage.
• At high surrounding temperatures and/or high heat sink temperatures (for example,
by preceding utilization nearby 100%) the drive converter can change to overtem-
perature error before triggering the protective function OL.
• At low output frequencies or switching frequencies higher than the rated switching fre-
quency, the frequency-dependent maximum current can be exceeded before and error
OL2 can be triggered (=> „Frequency-dependent maximum current (OL2) for 230V de-
