Selectable Kickstart
①
This feature provides a boost at startup to break away loads that
require a pulse of high torque to get started. This is intended to
provide a pulse of current that is 550% of full load current. Selectable
kickstart is user-adjustable from 0.0 to 2.0 seconds.

Current Limit Start
②
This starting mode provides a fixed reduced voltage start; it is used
when limiting maximum starting current is necessary. The Current
Limit level is user-adjustable from 50 to 600% of the motor full load
ampere rating; and the current limit time is user-adjustable from 0 to
30 seconds. If the SMC Dialog Plus controller senses that the motor
has reached the up-to-speed condition during the current limit starting
mode, the output voltage automatically switches to full voltage.

Kickstart is also available with Current Limit Start.
②
The Current Limit Start mode design is based on a motor with a locked rotor current rating that is
600% of the full load current rating.
