Smart Motor Braking Option
This option can be used in applications that require reduced stopping
times. The SMC Dialog Plus controller incorporates a
microprocessor-based system that applies braking current to a
standard squirrel cage induction motor without any additional
equipment. This option offers a user-adjustable braking current
setting from 0% to 400% of the motors full load current rating.
Further, it provides automatic shut-off at zero speed detection.
