Section V. Parameter Function Table
When upper limit is set through analog value or PULSE setup, P0.13 will be used as analog
valueoffset. The addition of offset frequency and analog setup value of frequency upper limit is used as
the final setup value of frequency upper limit.
P0.14
Frequency lower limit
0.00Hz to frequency upper limit P0.12 0.00Hz
☆
When the running frequency of the inverter is lower than the frequency lower limit, it can select to
run at frequency lower limit or stop the inverter. Refer to P8.14 function code for details.
P0.15
Carrier frequency
0.5kHz~16.0kHz
-
☆
This function is used to adjust the carrier frequency of the inverter. By adjusting the carrier
frequency, the motor noise can be reduced, the resonance of the mechanical system can be avoided, so
that the leakage current to the ground and the interference of the inverter can be reduced.
When the carrier wave frequency is low, the output current higher harmonic component will be
increased, the motor loss will be increased, and the motor temperature rise will also be increased.
When the carrier wave frequency is high, the motor loss is reduced, and the motor temperature
rise is reduced, but the inverter loss and inverter temperature rise will be increased, and thus the
interference will be increased.
The adjustment of carrier frequency will influence the following items on the performance
：
Carrier frequency
low→
high
Motor noise
big→ small
Output current waveform
poor→
well
Motor temperature rise
high→
low
Inverter temperature rise
low→
high
Leakage current
small→
large
Radiation interference
small→
big
Different power of inverter is set with different carrier frequency by the factory. Though user could
modify it , attention should be paid
：
if carrier frequency is set higher than the factory set valule, it will
lead to inverter radiator temperature rise increasing. User should take inverter derating use, or there
will be danger of overheating alarm.
P0.16

Carrier frequency adjusting with temperature refers to the detecting of radiator temperature. When
the temperature is high , carrier frequency automatically decreased to reduce the inverter temperature
rise. On the contrary , when the temperature is low, carrier frequency g radually restored to the set
value.This function could help to reduce the chance of inverter overheating alarm.
P0.17 Acceleration time 1 0.00s~65000s -
☆
P0.18
Deceleration time 1 0.00s~65000s -
☆
The acceleration time means the time t1 needed for the inverter to accelerate from 0Hz to the
reference frequency(P0.25).
The deceleration time means the time t2 needed for the inverter to decelerate from the reference
frequency (P0.25) to 0Hz.
The descriptionof acceleration and deceleration time are as shown in Fig.5.1
