At lower carrier frequency, output current of the drive produces higher harmonics, motor loss
increases, and temperature and motor noise rise, but drive temperature, drive leakage current, and
drive interference to external devices are lower or less.
With higher carrier frequency, drive temperature will rise, drive leakage current is bigger, and
drive interference to external devices is bigger. However, motor loss and noise will be lower, and
motor temperature will drop.
The table below specifies the setting range and factory default of PWM carrier frequency of the
drives at different power ratings:

PWM carrier frequency setting method:
1) When the motor line is too long, reduce carrier frequency.
2) When torque at low speed is unstable, reduce carrier frequency.
3) If the drive produces severe interference to surrounding equipment, reduce carrier frequency.
4) Leakage current of the drive is big, reduce carrier frequency.
5) Drive temperature rise is relatively high, reduce carrier frequency.
6) Motor temperature rise is relatively high, increase carrier frequency.
7) Motor noise is relatively big, increase carrier frequency.
ATTENTION:
Increasing carrier frequency can reduce motor noise and heat, but it will increase temperature of
inverter. When the carrier frequency is higher than the default, inverter rated power shall be decreased
by 5% for every additional 1 kHz carrier frequency.
F00.14
Upper carrier frequency
Range:0.700
～
16.000kHz
Default:8.000 kHz
F00.15
Lower carrier frequency
Range:0.700
～
16.000kHz
Default:2.000 kHz
Inverter carrier will vary with output frequency in linear variation. Upper/Lower carrier frequencies
are under control of F00.14 and F00.15.
F00.16
Output voltage
Range:5.0
～
150.0%
Default:150.0%
Adjust the percentage of output voltage to input voltage.
F00.17
AVR
Range:0
～
2
Default: 1
0: Disabled
1: Always be valid
Output voltage of inverter adjust automatically according to fluctuation of the bus voltage,to keep
output voltage constant.
2: Invalid when deceleration
AVR is invalid in the process of deceleration
。
F00.18
Fan control
Range:0
～
1
Default:1
After power is on, the fan runs per the control mode after running for 2 minutes regardless of the
working status of inverter.
0: The fan runs directly after inverter is power-on.
1: the fan works when the AC drive is in running state. When the AC drive stops, the cooling fan
works if the heat sink temperature is higher than 42°C, and stops working if the heat sink temperature
is lower than 38°C.
