Parameter Type Read & Write Minimum 0% of Drive Rated Current
When this parameter is set to zero, the [Current Limit]
setting is used throughout the frequency range. When set
to a value other than zero, the [Current Limit] value will
be active up to the [Base Frequency] setting, then tapers
down between [Base Frequency] and 1.5 times [Base
Frequency]. At frequencies above 1.5 times [Base
Frequency], the [Sec Curr Limit] setting is the active
current limit value.

Single Phase Input Ratings
The [Current Limit], [Overload Current] and [Sec Curr Limit] parameters are
set based on the drive rated output current for three phase input ratings. When
setting these parameters for single phase input ratings, use the following formula
to determine the proper parameter setting:
1-Phase Output Current x Percent (0 to 150%)
Three-Phase Output Current
= Parameter Setting in Percent
The Drive Rated Ouput Current is based on three phase input ratings. See Single
Phase Input Ratings instructions.
See Table 1.A on page 1-6.
