The SMC Dialog Plus controller can operate three-phase squirrel cage motors rated 1-1000A; 200-480V AC or 200-600V AC; 50/60 Hz. Depending upon the catalog number ordered, the controller will accept a control power input of either 100-240V AC or 24V AC/DC. If the control power input option is 100-240V AC, the controller’s microprocessor will self-adjust to the input control voltage.

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.

Selectable Kickstart

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.
