1-4 Product Overview
Starting Modes (cont.) Dual Ramp Start ①
This starting mode is useful on applications that have varying loads
(and therefore varying starting torque requirements). Dual Ramp
Start allows the user to select between two separate Soft Start profiles
with separately adjustable ramp times and initial torque settings.
