The soft starters can be adjusted as necessary for the application at hand by
using the three potentiometers, which are labeled U-Start, t-Start, and
t-Stop respectively. Aside from these potentiometer settings, no additional
settings or prompts are required in order to run the soft starters.
When using DS7-SWD soft starters, these potentiometer settings can be
adjusted by means of parameters.

￫ section 8.9, "Programming" explains how to configure the
DS7-SWD soft starter's parameters.
