Product Overview

Starting Modes

Soft Start

This mode 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 voltage to

the motor is steplessly increased during the acceleration ramp time.

The acceleration ramp 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 voltage ramp operation, the output

voltage automatically switches to full voltage.
