8 customized V/Fcurve
P0.22=4, Customized V/F curve shown as Fig. 6-8.
User can define V/F curve through revising (V1,F1),(V2,F2),(V3,F3) so as to meet special
load requirements. Torque boost is available for customized curve.

0.20s
When adopts frequency external analog channel setting mode, time constant is inverter
filtering sampling value time. When long distance wiring or serious interference cause setting
frequency unstable, increase this time constant to avoid the disoperation . The longer filtering
time, anti-interference ability will be stronger. But the response will be slower. The shorter
filtering time it has, the quicker response, but weaker anti-interference ability.
