2.5 Product Overview
An adjustable frequency drive (also called a drive) is an
electronic motor controller that converts DC 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 with
position sensors on a conveyor belt. The adjustable
frequency drive can also regulate the motor by responding
to remote commands from external controllers.
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
Operation and monitoring functions are available as status
indications to an outside control system or serial communi-
cation network.
A Low Harmonic Drive (LHD) is a single unit that combines
the adjustable frequency drive with an advanced active
filter (AAF) for harmonic mitigation. The adjustable
frequency drive and filter are two separate pieces
packaged together in an integrated system, but each
functions independently. In this manual, there are separate
specifications for the adjustable frequency drive and the
filter. Since the adjustable frequency drive and filter are
together in the same enclosure, the unit is transported,
installed, and operated as a single entity.
