NOTE!
The currents in given ambient temperatures (in 9.2 Vacon® NXS and NXP -
technical data) are achieved only when the switching frequency is the same or
smaller than the factory default.
The currents for FR10 to FR11 are valid at an ambient temperature of 40°C (104 °F) (except
for 0416 6 and 0590 6: currents are valid at an ambient temperature of 35°C (95 °F)).

OVERLOAD CAPABILITY
The low overload means that if 110% of the continuous current (I
each 10 minutes, the remaining 9 minutes must be approximately 98% of I
make sure that the output current is not more than I
