Figure 4.38 Bottle Filler with Soft Start and Soft Stop Option
Problem: A bottle filler line had product spillage during starting
and stopping. An across-the-line starter was used to start
the motor. In addition, the application required an
auxiliary contact that would energize when the motor was
up to speed.
Solution: The SMC Dialog Plus controller was installed and
programmed for a 13-second soft start with an 18-second
soft stop. The controlled start reduced the starting torqu
and, consequently, the product spillage. The Soft Stop
option extended the stopping time, smoothing load shift
while stopping. The auxiliary contacts were configured
to change state when the motor was up to speed.
