4-32 Application Profiles for the SMC Dialog Plus Controller
Figure 4.31 Chain Conveyor with Soft Start and Soft Stop Option
Problem: A chain conveyor was used to transport automobile
windshields to a packaging area. The high starting
torque would cause the load to shift, damaging th
windshields. The stopping of the conveyor also caused
shifting problems when the load decelerated quickly. An
across-the-line starter was used in this application.
Because the cost of downtime was high, a modular
controller was required for ease of maintenance.
Solution: The SMC Dialog Plus controller with the Soft Stop
option was installed, reducing the starting torque and
decreasing the product shift on start-up. The Soft Stop
option extended the stopping time, bringing the conveyor
to a smooth stop. The SMC Dialog Plus controller has a
plug-in control module and power poles. Th
programming could be bench-adjusted for the desired
ramp parameters and quickly replaced.
