LEESON FHP Series NEMA 4x Variable Speed Drive - Manual (Page 4)

iii General Information
Many 3-phase inverter manufacturers claim that they can
run single-phase motors effectively. This is normally
accomplished by wiring only 2 phases; however, this
method may cause instabilities due to the lack of feedback
from one of the motor connections. Furthermore, motor
torque will be reduced considerably because the phases
are 120° apart. Although the FHP Series uses this method
of
connection, its fundamental design enables it to operate
efficiently under these conditions.
The FHP Series features solid-state reversing with
adjustable acceleration and deceleration. The FHP Series
may
also interface with motor thermal protection through
the
enable circuit.
