Soft Start with Selectable Kickstart
This method has the most general application. The motor is given an
initial torque setting, which is user adjustable from 0 to 90% of
locked rotor torque. From the initial torque level, the output voltag
to the motor is steplessly increased during the acceleration ramp time,
which is user adjustable from 0 to 30 seconds. If, during the voltag
ramp operation, the SMC Dialog Plus controller senses that the moto
has reached an up-to-speed condition, the output voltage will
automatically switch to full voltage.
The kickstart feature provides a boost at start-up to break away loads
that may require a pulse of high torque to get started. It is intended to
provide a current pulse of 550% of full load current and is user
adjustable from 0.0 to 2.0 seconds.
