NOTE!
The currents in given ambient temperatures (in chapter 10.2 Vacon® 100 HVAC -
technical data) are achieved only when the switching frequency is equal to or less
than the factory default.
10.1.3
OVERLOAD CAPABILITY
The low overload means that if 110% of the continuous current (I
L
) is required for 1 minute
every 10 minutes, the remaining 9 minutes must be approximately 98% of I
L
or less. This is to
make sure that the output current is not more than I
L
during the duty cycle.
