3.3.4.1 Overload characteristic (OL)
All COMBIVERT S6 can be operated time-limited at rated switching frequency even in
overload.Further information can be found in the diagrams “Turn-off time depending on
the overload at unit size 12 and 13” and “Turn-off time depending on the overload at unit
size 14” .
Restrictions:
• The thermal design of the heat sink is based on the rated current and the maximum
surrounding temperature. At high surrounding temperatures and/or high heat sink
temperatures (for example, by preceding utilization nearby 100%), the drive con-
verter can change to overtemperature error before triggering the protective function
OL.
• At low output frequencies or switching frequencies higher than the rated switching
frequency, the maximum current (I0Hz/I6Hz) can be exceeded before and the error
OL2 can be triggered (see also chapter "Maximum current (OL2)“).
On exceeding a load of 105% the overload integrator starts. When falling below the in-
tegrator counts backwards. If the integrator achieves the overload characteristic, „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 down phase.
