3.5 Additional Inputs and Outputs
3.5.1 Wiring Schematic
When wired and properly programmed, the control terminals provide:
•
Feedback, reference, and other input signals to the adjustable frequency drive.
•
Output status and fault conditions from the adjustable frequency drive.
•
Relays to operate auxiliary equipment.
•
A serial communication interface.
•
24 V common.
Control terminals are programmable for various functions by selecting parameter options through the local control panel
(LCP) on the front of the unit or external sources. Most control wiring is customer-supplied, unless specied in the factory
order.
