UNIT DATA

3.3.4.4 Maximum current (OL2)

It can be adjusted in the drive converter parameters if error (OL2) shall be triggered
when exceeding the maximum currents, or if the switching frequency is automatically
reduced (derating).
The following tables indicate the permissible maximum current for 6 output frequency
values. In between there is a linear interpolation. Unit size 13 is represented exemplary.
