Control
This group of parameters defines basic motor control.
[Control Select]
Selectsthemotorcontrolmethodforthedrive.Thedefault
setting provides full stator flux control that is suitable for
most applications.
Additional selections are offered to optimally tune
performance:
• Two volts/Hertz modesare available; oneusing simple
voltage boost and one for complete configurability.
Thesemayberequiredforspecialmotorsorunmatched
multi-motor installations.
• TheEconomizemodeoffersalltheadvantagesofstator
flux control plus the added feature of an “auto-econo-
mizer.” If a motor remains lightly loaded, the drive will
reduce output voltage (and therefore output kW) in or-
dertoreduce theenergy(operating)costs ofthelightly
loadedmotor.This canresultin upto 20%kW savings.

[Flux Amps Ref]
Used in “Economize” & “Sens Vector” modes - Sets the
valueofamps requiredto maintainfull motorflux.If setto
zero, the drive willuse an internal value basedon [Motor
