3.6 Additional Inputs and Outputs
3.6.1 Wiring Schematic
When wired and properly programmed, the control terminals provide:
•
Feedback, reference, and other input signals to the frequency converter.
•
Output status and fault conditions from the frequency converter.
•
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 through external sources. Most control wiring is customer-supplied, unless specified in the
factory order.
