7 - PARAMETER DESCRIPTION
LCD Display
Range 0.6 to 16.0 kHz (Default 3.0 kHz)
Description This parameter congures the switching (or carrier) frequency for the drive. Lower frequencies produce
better torque, but produce more audible noise from the motor. Higher switching frequencies produce less
audible noise, but cause more heating in the drive and motor.
z NOTE: This parameter is not adjustable during Run mode.
See also page 34 for information on motor lead lengths.
High carrier frequencies and long lead lengths can lead to premature motor and/or drive failure.

Parameter Value Description
No (Default)
Slip compensation is not utilized
Yes
The drive calculates how much slip compensation is needed depending on the load and motor speed
Description This parameter sets the amounts of slip compensation which may help maintain constant motor speed
under changing load conditions.
V-BoostConf AFN07
AFN: V-Boost Conf
07 1.0%
LCD Display
Range 0.00 to 50% (Default 1.0%)
Description This parameter sets the amount of boost (expressed as a percentage of nominal motor voltage) to be applied
at zero frequency. The amount congured then tapers linearly as frequency increases, reaching zero at the
point specied by parameters AFN 08 - Bst Tpr Frq and AFN 09 - Bst Tpr Vlt.
This parameter is used when FUN 02 - Torque Curve is set to Linear Fxd, Linear Auto, Pump Fxd, or Fan
Fxd.
z NOTE: This parameter is not used when the drive is in Vector mode.
