If the carrier frequency is high, power loss and temperature rise of the motor declines. However,
the inverter has an increase in power loss, temperature rise and interference.
Adjusting the carrier frequency will exert influences on the aspects listed in the following table.

The factory setting of carrier frequency varies with the inverter power. If you need to modify the
carrier frequency, note that if the set carrier frequency is higher than factory setting, it will lead to an
increase in temperature rise of the inverter's heatsink. In this case, you need to de-rate the inverter.
Otherwise, the inverter may overheat and alarm.

It is used to set whether the carrier frequency is adjusted based on the temperature. The Inverter
automatically reduces the carrier frequency when detecting that the heatsink temperature is high. The
Inverter resumes the carrier frequency to the set value when the heatsink temperature becomes
normal. This function reduces the overheat alarms.

Acceleration time indicates the time required by the Inverter to accelerate from 0 Hz to
"Acceleration/Deceleration base frequency" (P0.25), that is, t1 in Figure below.
Deceleration time indicates the time required by the Inverter to decelerate from
"Acceleration/Deceleration base frequency" (P0.25) to 0 Hz, that is, t2 in figure below.
