F0.16 Carrier wave frequency
Setting range： 1.5 ~ 10.0 KHz
Carrier wave frequency influences audio-frequency noise and calorific effect in running.
When environmental temperature is too high and motor’s load is too heavy, carrier frequency should be decreased
properly to improve the heat thermal performance.
F0.17 Carrier wave characteristics
Setting range：0000 ~ 1110
It is used for setting correlated characteristics about carrier wave.
The first part of LED (form right to left): Reserved
The second part of LED：Load relating carrier wave adjustment.
If this function is valid, when load current is too high, it will automatically reduce the carrier frequency to ensure
operation safety of inverter.
0：Invalid
1：Valid
The third part of LED：Heat relating carrier wave adjustment
If this function is valid, when environmental temperature is too high, the inverter will automatically reduce the carrier
wave frequency.
0：Invalid
1：Valid
The fourth part of LED：Freq. relating carrier wave adjustment
If this function is valid, the inverter will automatically reduce the carrier frequency in low-frequency running.
0：Invalid
1：Valid
Attention：When the inverter automatically adjusts carrier freq., the running noise will increase
F0.18 Parameter write-protect
Setting range：1，2
It is used for preventing error modify about data.
1：Forbid to modify all parameter, except F0.2 and F0.18
2：Forbid to modify all parameter, except F0.18
Parameter F0.4 is valid together with direction control of external terminals.
6.2 Primary application of parameter unit
The parameter sets [F1.0]-[F1.10] are used for setting V/F curve during V/F control mode. V/F curve
type (parameter [F1.0]) can be freely selected and set according to the load type. To solve the defect
that the low-frequency torque of V/F control method is insufficient, setting of the torque
compensation can boost the output torque, and substantially increase the output voltage value of the
inverter to enhance the output current of the inverter; the torque boosting function can be specifically
set according to [F1.1]-[F1.2] parameters. Parameters [F1.5]-[1.10] are used for determining the
curve setting during customized output of V/F curve, and please refer to the parameter description
for the details
F1.0 Type of V/F Curve
Setting range ：0 ~ 3
0：Constant torque curve
The output voltage of inverter is in direct ratio to the output frequency, and most load take this mode.
1: low-freq. torque curve 1
The output voltage of inverter is conic with the output frequency, which is suited to the fan and pump load.
2: low-freq. torque curve
The output voltage of inverter is conic with the output frequency, which is suited to the constant power load, such as
