Increasing carrier frequency can reduce motor noise, but it will increase inverter heat
as well. When the carrier frequency is higher than the default value, increasing the carrier
frequency by 1 kHz requires the load to decrease to some extent. Please set F00.24=1,
and at this time, inverter will automatically adjust the actual carrier frequency based upon
the actual condition.
It's recommend to set the relationship between inverter’s rated power and carrier
frequency as shown in Table 7–2.

Inverter judges the direction according to the status of terminal F/R and
the value set through F00.20. If the set forward direction is inconsistent
with the wished motor direction, switch any two of inverter’s output terminals
U, V and W, or change F00.20 to an inverse value.
