Parameter Reference
0447
Fixed Boost
This parameter allows for no-load stator resistance voltage
drop compensation. This correctly fluxes the motor (under no-
load conditions) at low output frequencies, thereby increasing
available motor torque. Fixed boost can be set in addition to
auto boost and acceleration boost.
0448
Auto Boost
This parameter allows for load dependent stator resistance voltage drop compensation. This correctly fluxes the motor (under load
conditions) at low output frequencies, thereby increasing available motor torque. Auto Boost can be set in addition to Fixed Boost.
The value of the Auto Boost parameter determines level of additional volts supplied to the motor for 100% load.
Setting the value of auto boost too high can cause the Drive to enter current limit. If this occurs, the Drive will be unable to ramp up in
speed. Reducing the value of auto boost will eliminate this problem.
0450
Acceleration Boost
Additional amount of fixed boost when the drive is accelerating.
0451
Energy Saving Enable
Enable/Disable energy saving mode to minimize energy consumption.
