Description of Function Codes
Adjusting the carrier frequency will exert influences on the aspects listed in the following
table.
Table 6-1 Influences of carrier frequency adjustment
Carrier frequency
Motor noise
Output current waveform
Motor temperature rise
AC drive temperature rise
Leakage current
External radiation
interference
The factory setting of carrier frequency varies with the AC drive 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 AC drive's heatsink. In this case, you need
to de-rate the AC drive. Otherwise, the AC drive may overheat and alarm.
Function Code
Carrier frequency adjustment with
P0-16
temperature
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.

P0-18
Acceleration time indicates the time required by the AC drive to accelerate from 0 Hz to
"Acceleration/Deceleration base frequency" (P0-25), that is, t1 in Figure 6-2.
Deceleration time indicates the time required by the AC drive to decelerate from
"Acceleration/Deceleration base frequency" (P0-25) to 0 Hz, that is, t2 in Figure 6-2.
