SMC-2 Smart Motor Controller 2-15
Figure 2.17 Bottle Filler with Soft Start and Soft Stop Option
Problem: A bottle filler line had product spillage upon starting and
stopping. An across-the-line starter was used to start th
motor. In addition, the application required an auxiliary
contact that would energize when the motor was up to
speed.
Solution: The SMC-2 controller was installed and set for a 10-
second soft start with a 20-second soft stop. This
controlled the starting torque and prevented the sudden
start that would cause the bottles to spill. The soft stop
extended the stopping time eliminating load shift while
stopping. The auxiliary contact was configured to
change state when the motor was up to speed.
