Application Profiles for the SMC Dialog Plus Controller
Figure 4.33 Die Changer with Soft Start and Accu-Stop Option
Problem: A die changer on a press required frequent jogging to
move the die into position. An across-the-line starter was
being used. When new operators controlled the press, the
set-up time increased, because more trial and error
occurred in positioning. The application required
reduced speed as the die neared the press. The company
was also looking into automating the die changing
process with the use of a PLC. A controller with
communications capabilities was a plus.
Solution: The SMC Dialog Plus controller with the Accu-Stop
option was installed on both carts. The motor was soft
started. As the cart neared the press, it decelerated to th
preset slow speed (15%). A braking action would then
stop the cart in the proper position. This reduced the time
previously required to position the die. The built-in
communications capabilities of the SMC Dialog Plus
controller made it possible to communicate with many
different protocols, leaving several network options
available to the company.
