10.3.2 Vector control
Compared with the V/f characteristic control the vector control offers
considerably higher torque and lower current consumption during idle running.
The vector control is an improved motor current control following the Lenze FTC
technology. Select vector control for operation of the following drives:
l Single drives with extremely changing loads
l Single drives with heavy start conditions
l Sensorless speed control of standard three-phase AC motors
)
))
) Note!
l The connected motor should maximally be two power classes
lower than the motor assigned to the controller.
l The operation with vector control is not possible if several
drives are operated on one controller.
l The motor parameter identification is absolutely vital!
Otherwise commissioning is not possible.
