Parameter Descriptions
FIXED BOOST
PREF: 21.03
Default: 0.00 %
Range: 0.00 to 25.00 %
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.

AUTO BOOST
PREF: 21.04
Default: 0.00 %
Range: 0.00 to 25.00 %
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.
ACCELRTN BOOST
PREF: 21.08
Default:0.00 %
Range: 0.00 to 25.00 %
This parameter provides an additional amount of fixed boost when the drive is accelerating. This can help when starting heavy/high stiction loads.
ENERGY SAVING
PREF: 21.09
Default: FALSE
Range: FALSE / TRUE
When set TRUE, the demanded volts are reduced to minimise energy consumption if the drive is operating in a steady state at light load.
