4-38 Application Profiles for the SMC Dialog Plus Controller
Figure 4.37 Rotary Table with Soft Start and Accu-Stop Option
Problem: A machining process required a station change to attach a
different tool. The part had to be jogged into position
before the tool could be changed. The tool was replaced
approximately three times per hour. Since the majority
of the operation was controlled through a PLC,
communications capability was required. The customer
did not need the functionality of more costly motor-
positioning methods.
Solution: The SMC Dialog Plus controller with the Accu-Stop
option was installed, allowing the part to be positioned
into the station at a slow speed. The controller was set to
brake the rotary table to a preset slow speed and then to
stop the table in the proper location. The Accu-Stop
option provided the position control required without
jogging the motor, thereby increasing the productivity of
the rotary table station. The built-in communications
feature of the SMC Dialog Plus controller provided
communication to the PLC controlling the rest of th
operation.
