Motor
Control
This group of parameters defines basic motor control.
[Control Select]
Selects the motor control method for the drive. The default
setting provides full stator flux control that is suitable for
most applications.
Important: When using synchronous motors, [Control Se-
lect] must be set to V/Hz operation (“Fixed Boost” or “Full
Custom”).
Additional selections are offered to optimally tune
performance:
• Two volts/Hertz modes are available; one using simple
voltage boost and one for complete configurability.
These may be required for special motors or unmatched
multi-motor installations.
• The Economize mode offers all the advantages of stator
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-
der to reduce the energy (operating) costs of the lightly
loaded motor. This can result in up to 20% kW savings.

[Flux Amps Ref]
Used in “Economize” & “Sens Vector” modes - Sets the
value of amps required to maintain full motor flux. If set to
zero, the drive will use an internal value based on [Motor
NP Amps] and drive kW (HP). Refer to Chapter 5 for setup
information.
