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.
