3 System Integration
3.1 Introduction
This chapter describes the considerations necessary to
integrate the frequency converter into a system design.
The chapter is divided into 4 sections:
•
Ambient operating conditions for the converter
including environment, enclosures, temperature,
derating, and other considerations
(
chapter 3.6 Ambient Conditions
)
•
Input into the converter from the mains side
including power, harmonics, monitoring, cabling,
fusing, and other considerations
(
)
•
Output from the converter to the motor including
motor types, load, monitoring, cabling, and other
considerations (
•
Integration of the converter input and output for
optimal system design including converter/motor
matching, system characteristics, and other
considerations (
chapter 3.4 Frequency Converter/
3.1.1 FCM 106 - Integrated Frequency
Converter and Motor
The Danfoss VLT frequency converter integrated onto the
asynchronous or permanent magnet motor enables speed
control in a single unit.
The FCM 106 is a very compact alternative to a central
solution where the frequency converter and motor are
installed as separate units.
•
No cabinet is required
•
The frequency converter is mounted directly onto
the motor, instead of connecting via the motor
terminal box
•
Electrical installation involves mains and control
connections only. There is no need for special
details on wiring to meet the EMC directive, since
motor cables are not necessary.
Factory-set adaption between FCM 106 and the motor
gives precise and energy efficient control in addition to
eliminating pre-setting on site.
The FCM 106 can be used in stand-alone systems with
traditional control signals, such as start/stop signals, speed
references and closed loop process control or in multiple
drive systems with control signals distributed by a field
bus.
Combined fieldbus and traditional control signals with
closed loop PI control is possible.
