It is used to set whether the carrier frequency is adjusted based on the temperature. The
AC drive automatically reduces the carrier frequency when detecting that the heatsink
temperature is high. The AC drive 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 AC drive to accelerate from 0 Hz to
"Acceleration/Deceleration base frequency" (F0-25), that is, t1 in Figure 6-2.
Deceleration time indicates the time required by the AC drive to decelerate from
"Acceleration/Deceleration base frequency" (F0-25) to 0 Hz, that is, t2 in Figure 6-2.
