3.2.3.2 Frequency-dependent maximum current (OL2)

The characteristics of the maximum currents for a switching frequency which are de-

pending on the output frequency are different for each drive converter, but the following

general rules apply are generally applicable:

•

In the drive converter parameters can be adjusted, if error (OL2) shall be triggered on

exceeding the maximum currents or if the switching frequency is automatically reduced

(Derating).

Applies for the rated switching frequency: at 0 Hz output frequency the drive convert-

er can provide at least the rated output current.

Lower maximum currents apply for switching frequencies > rated switching frequen-

cy.
