Goodrive3000 series medium voltage VFD Goodrive3000 PWM rectifier
-30-
The absolute value of the difference between the setting value and feedback value of DC voltage is
∆.
When
∆ is less than P03.15, it will apply PI parameter 1; when ∆ is more than (or equal to) P03.15, it will
apply PI parameter 2.

Note:
The setting value of power factor is only valid in COS
φ operation mode and current close-loop operation
mode.
P03.19
–P03.23 are used to set the power factor in COSφ running mode by using the angle between
voltage and current or by direct setting. The following figures show the relationship between the power
factor and the angle. When the angle is used for power factor setting, this function code group is used to
determine θ. When the power factor is directly set, this function code group is used to determine cosθ.
