4-36 Application Profiles for the SMC Dialog Plus Controller
Figure 4.35 Grinder with Soft Start and SMB Smart Motor Braking Option
Problem: A grinder application used a soft start and a separat
braking package to start and stop the motor. This method
was functionally acceptable, but required extra power
wiring and contactors. Additional panel space and
adjustments were required to interlock the soft start and
brake, which meant a larger control panel and added cost
to the package.
Solution: The SMC Dialog Plus controller with the SMB Smart
Motor Braking option was installed. The soft start
reduced the starting torque, protecting against damage to
the gearbox. The SMB Smart Motor Braking option
stopped the grinder quickly. This option required no
additional panel space or power wiring. The power
wiring, installation and programming of the SMC Dialog
Plus controller were easier to use than previous methods,
and the cost of the control package was significantly
reduced.
