Current Limit Start
This starting method provides a fixed reduced voltage start and is
used when it is necessary to limit the maximum starting current. Th
starting current is user adjustable from 50 to 600% of full load
amperes. The current limit starting time is user adjustable from 0 to
30 seconds.

Dual Ramp Start
This starting method is useful on applications with varying loads and
varying starting torque requirements. Dual Ramp Start offers the user
the ability to select between two separate Soft Start profiles with
separately adjustable ramp times and initial torque settings.
