Fixed Boost

The value of the

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.

Parameter Reference

V/F Shape

The function allows the user to parameterise the Drive’s conventional V/F motor fluxing scheme. Four V/F shapes are available, LINEAR LAW, FAN
LAW, USER DEFINED, and APPLICATION DEFINED:

♦

Linear Law V/F shape should be used in applications requiring constant motor torque though out the speed range (e.g. machine tools or
hoists).

♦

Fan Law V/F shape provides less torque capabilities for lower speeds, which means some energy savings can be achieved for fan or
pump applications when they operate at lower speed/load setpoints. When choosing fan law shape the user should carefully consider if
such profile is suitable for the overall load cycle of their application.

♦

User Defined V/F shape provides a method for the user to define any profile. 10 user definable (x,y) points are provided. Linear
interpolation is used between each point. The drive also assumes the following points - (0%,0%) and (100%,100%) - though these may
be overridden. For example, (USER FREQ 1 = 0%, USER VOLTAGE 1 = 5%) takes precedence over (0%, 0%).

♦

Application Defined V/F shape provides a method for the user to define any fluxing profile within the application layer. In the application
the user can set desired voltage level for any operating frequency, and the application will dynamically provide that value to the
firmware, via the “Application Volts” parameter. If this mode is used, it is recommended that such application is executed in 1ms time
frame.

For any of these V/F shapes the

Base Frequency

parameter (in the

Motor Nameplate

function) which is the value of Drive output frequency at

which maximum output volts is provided, can be set by the user.

Boost Parameters

♦

Correct no-load motor fluxing at low Drive output frequencies can be achieved by setting the

Fixed Boost

parameter.

♦

Correct motor fluxing under load conditions is achieved by setting the

Auto Boost

parameter. The motor is correctly fluxed when the

Actual Field Current

diagnostic in the

Feedbacks

function reads 100.0% .

♦

Additional

Fixed

Boost

can be applied during acceleration by setting the

Acceleration Boost

parameter. This can be useful for starting

heavy/high stiction loads.

Saving Energy

Energy Saving

mode is provided to allow the user to choose to optimize energy consumption under low load conditions in steady state. As soon

as the load is increased or acceleration is required, the drive suspends energy saving mode, and returns to it only if the load conditions are such that
it is allowed to do so. If enabled, energy saving mode is reducing the voltage of the motor to a level required to maintain specific setpoint speed at a
particular low load. For sustained low load conditions it is not necessary to keep the motor fluxed for rated torque capabilities, so the motor voltage is
