Danfoss VLT Midi Drive FC 280 Design Guide

1 Introduction
1.1 Purpose of the Design Guide
This design guide is intended for project and systems
engineers, design consultants, and application and product
specialists. Technical information is provided to understand
the capabilities of the frequency converter for integration
into motor control and monitoring systems. Details
concerning operation, requirements, and recommendations
for system integration are described. Information is
provided for input power characteristics, output for motor
control, and ambient operating conditions for the
frequency converter.
Also included are:
•
Safety features.
•
Fault condition monitoring.
•
Operational status reporting.
•
Serial communication capabilities.
•
Programmable options and features.
Design details such as site requirements, cables, fuses,
control wiring, the size and weight of units, and other
critical information necessary to plan for system integration
are also provided.
Reviewing the detailed product information in the design
stage enables developing a well-conceived system with
optimal functionality and
eciency.
