1.1 Purpose of the Manual
This manual is intended to provide detailed information for
the installation and start-up of the adjustable frequency
drive. provides requirements for mechanical and electrical
installation, including input, motor, control and serial
communications wiring, and control terminal functions.
provides detailed procedures for start-up, basic operational
programming, and functional testing. The remaining
chapters provide supplementary details. These details
include user interface, detailed programming, application
examples, start-up troubleshooting, and specifications.
1.2 Additional
Resources
Other resources are available to understand advanced
adjustable frequency drive functions and programming.
•
The
AF-600 FP Programming Guide, DET-618
provides greater detail on working with
parameters and many application examples.
•
Optional equipment is available that may change
some of the procedures described. Reference the
instructions supplied with those options for
specific requirements. Contact the local GE
supplier or visit the GE website for downloads or
additional information.
1.3 Product
Overview
An adjustable frequency drive is an electronic motor
controller that converts AC line power input into a variable
AC waveform output. The frequency and voltage of the
output are regulated to control the motor speed or torque.
The adjustable frequency drive can vary the speed of the
motor in response to system feedback, such as changing
temperature or pressure for controlling fan, compressor, or
pump motors. The adjustable frequency drive can also
regulate the motor by responding to remote commands
from external controllers.
In addition, the adjustable frequency drive monitors the
system and motor status, issues warnings or alarms for
fault conditions, starts and stops the motor, optimizes
energy efficiency, and offers many more control,
monitoring, and efficiency functions. Operation and
monitoring functions are available as status indications to
an outside control system or serial communication
network.
