gefran AFE200 Series

78 AFE200 • Instruction Manual
5 - REFERENCE
AFE drives have a DC-link voltage regulation circuit; which can be adapted to suit the various appli-
cations. In the standard version, the regulator has PI behaviour and the regulator parameters are the
same for the entire eld of regulation.

5.1 600 Dig DC voltage ref V FLOAT CALCF CALCF CALCF RW
Setting of the digital reference for the DC-link voltage ramp. This reference sets the
ramp voltage that the DC-link must reach after the acceleration phase.
Variations in the ramp reference are made with the selected ramp times.

5.2 288 Reactive current ref A FLOAT 0.0 0.0 CALCF RW
Setting of the reference value for the reactive current to be supplied by the AFE200 to
the mains.

5.4 604 Deceleration time DC s FLOAT 5.0 0.0 20.0 RW
The acceleration and deceleration ramp times are used to avoid sudden changes
in the DC bus voltage. The acceleration time is expressed as the time needed to in-
crease the voltage from zero to the maximum value (AFE200-4/4A = 875 V, AFE200-
6/6A = 1300V). The deceleration time is expressed as the time needed to reduce the
frequency from the maximum value to zero.

L�VREF
Selection of the origin (source) of the DC voltage reference signal. The signal used for
this function can be set from among those available in the “L_VREF” selection list.
