Product Overview
Operation
The SMC-Flex controller can operate standard squirrel-cage
induction motors rated 1…1250 A or Star-delta (wye-delta) type
motors rated 1.8…1600 A; up to 690V AC, 50/60 Hz. Depending
upon the controller type ordered, the control power input can range
from 100…240V AC to 24V AC/DC. Please verify voltage on
product, before applying power.
Modes of Operation (Standard)
Soft Start
①
This mode has the most general application. The motor is given an
initial torque setting, which is user-adjustable from 0…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…30 seconds. If the
SMC-Flex controller senses that the motor has reached the up-to-
speed condition during the voltage ramp operation, the internal
bypass contactor will be pulled in.
