44 SUNFAR C300
C300 series of non-sensor current vector-control inverter manual
Parameters F0.13 and F0.14 define characteristics of S curve. It is totally divided
into three sections, shown as fig6-3.
Acc/Dec initial section is the process that slope of output freq. is increase form 0
gradually. The slope will fix in Acc/Dec ascending/decline section. And the slope will
decrease to 0 gradually in end section.
The parameter has decided the switch frequency of the inner frequency of inverter.
As to the different power of inverter, there are differences between the highest
carrier wave frequency and the lowest carrier wave frequency under permission.
Carrier wave frequency mainly influences audio-frequency noise and calorific effect
in running. If you need the running situation that you can heighten the carrier wave
frequency a little, while the load capacity of inverter would decrease a little, and the
interference rates of inverter would increase little.
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.
It used for setting correlative characteristics about carrier wave.
It is used for preventing error modify about data.

In running, some parameters cannot be modified. At this time , if try to modify
these parameters, the inverter will display “— —”, please turn off the inverter
