7 - PARAMETER DESCRIPTION
LCD Display
Range 0.00 to Max Freq (Default 60Hz)
Description This parameter works with the AFN 07 - V-Boost Conf and AFN 09 - boost taper voltage parameter. When
voltage boost is applied at the start of the V/Hz curve, the amount of boost tapers linearly and reaches zero
at the point established by the frequency set in this parameter and the voltage set in parameter AFN 09 -
Bst. Tpr Vlt.

Range 0.00 to 100.00% (Default 100.0%)
Description This parameter works with the AFN 07 - V-Boost Conf parameters. When voltage boost is applied at the
start of the V/Hz curve, the amount of boost tapers linearly and reaches zero at the point established by the
voltage set in this parameter and the frequency set in parameter AFN 08 - Bst. Tpr Frq
z NOTE: In variable torque mode, Boost Taper voltage and frequency are locked at 100%
