3-8 SMC Dialog Plus Smart Motor Controller
Features (cont.) Auxiliary Contacts
Three hard contacts are provided as standard with the SMC Dialog
Plus controller. The first two contacts are programmable for Normal/
Up-to-speed. The third contact is programmable for Normal/Fault.
Energy Saver
The built-in Energy Saver feature is integral to the SMC Dialog Plus
controller and may be applied to applications where the motor is
lightly loaded or unloaded for long periods of time. With the Energy
Saver feature enabled, the SMC Dialog Plus controller continuously
monitors the loading of the motor with its internal feedback circuitry.
Because the output voltage is SCR controlled, motor power losses can
be reduced by decreasing the motor terminal voltage.
Note: The Energy Saver feature is not available when a bypass
contactor is used.
Modular Design
The SMC Dialog Plus controller packaging is designed for industrial
environments. The modularity of control and power modules featur
plug-in functionality. There are no gate wires to remove and no
soldering is required. Common control modules reduce inventory
requirements.
