DCS500 Pin and Parameter list
A 32
GENER.WEAK_POINT
Parameter of EMF_CONTROL-function block (S8/16 | S21.232)
This parameter has a similar function than FIELD_WEAK_POINT. It specifies the speed of
the motor where flux reference reduction is started, if the drive is in regenerative mode.
This function becomes active, if the value is lower than the one of FIELD_WEAK_POINT.

FIELD_WEAK_DELAY
Parameter of EMF_CONTROL-function block (S8/16 | S21.233)
This parameter defines a time delay, which will delay a reduction of the field current in
case different field weakening points are set (see GENER.EMF_REF /
GENER.WEAK_POINT) and the drive starts field weakening very often because of a high
gain at the speed controller. This time delay will give the speed controller a chance to
“correct” himself and avoid a bridge reversal.
