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
the overload at unit size 12 and 13"
size
Restrictions:

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.

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)").
