Fig.8-19: Square V/F curve auto torque boost
S0.22 I*R boost factor
Setting range 0%~320%
Minimum unit 1%
Factory default 100%
Used for further adjustment of the voltage boost. Its default value is 100 % which
means no adjustment is needed. The formula is shown as below:
Fig.8-20: Voltage boost
R : stator resistance
1
I : stator current
1
Thus, R should be preset or calculated or tuned, and then input to [S2.10].
1
S0.24 Heavy load voltage stabilization
Setting range 0: disable; 1: enable
Minimum unit 1
Factory default 1
Used to depress the fluctuations in output voltage and current, which are caused by
bigger impact to DC bus voltage in case of heavy load.
