SVX9000 Adjustable Frequency Drives
Product Family Overview
Controller Features
Operator Control and Interface
Requirements
Since there are many possible configu-
rations and many ways of achieving a
specific end result, it pays to consider
the operator control and interface
requirements carefully. A simplified
and more economical drive package
can often be achieved by selecting
from standard product offerings rather
than specifying a custom designed
configuration.
Installation Compatibility
The successful application of an AC
drive requires the assurance that the
drive will be compatible with the envi-
ronment in which it will be installed. In
planning the installation, be sure to
carefully consider the heat produced
by the drive, the altitude and tempera-
ture limits and the need for clean cool-
ing air. Other important considerations
include acoustical noise, vibration,
electromagnetic compatibility, power
quality, controller input harmonic cur-
rent and power distribution equipment
requirements.
Auxiliary Equipment and Accessories
Adjustable drives are generally
designed to have a motor directly
connected to the controller output
terminals with no other equipment
connected in series or parallel. Motor
starters, disconnect switches, surge
absorbers, dv/dt suppression circuits,
output chokes, output transformers
and any other equipment under con-
sideration for installation on the output
of the controller should not be installed
without first requesting Application
Engineering assistance. Power factor
correction capacitors must never,
under any circumstances, be con-
nected at the output of the controller.
They would serve no useful purpose,
and they may damage the controller.
Enclosure Definitions
■
NEMA Type 1
— Enclosures are
intended for indoor use primarily to
provide a degree of protection
against contact with enclosed equip-
ment and provide a degree of pro-
tection against a limited amount of
falling dirt in locations where
unusual service conditions do not
exist. Top or side openings in the
NEMA Type 1 enclosure allow for
the free exchange of inside and out-
side air while meeting the UL rod
entry and rust resistance design
tests.
■
NEMA Type 12
— Enclosures are
intended for indoor use primarily
to provide a degree of protection
against circulating dust, falling dirt
and dripping noncorrosive liquids.
To meet UL drip, dust and rust
resistance tests, NEMA Type 12
enclosures have no openings to
allow for the exchange of inside
and outside air.
■
Chassis IP00
— Similar to Protected
Chassis IP20 except power terminals
are protected by plastic shielding
only. Primarily intended to be
mounted inside a surrounding
protective enclosure.
■
NEMA 3R
— Similar in design to
NEMA Type 12 except with more strin-
gent design and test requirements.
Motor Protection
DV/DT and Peak Motor Voltage Solutions
Today’s AFD products offer signifi-
cantly improved performance, but at
the potential cost of motor insulation
stress. The fast switching time of the
IGBT devices used in newer AFDs can
cause a transmission line effect in
the output power leads to the motor,
leading to possibly damaging voltage
levels. To meet this need, NEMA has
introduced a motor in MG1, Part 31,
which provides an insulation system
designed to maintain normal motor
life in AFD applications. For existing
motors, a motor protection scheme is
required for longer cable runs. Eaton
offers three standard solutions for
existing systems.
■
MotoRx
This patented Cutler-Hammer solu-
tion provides an energy recovery
system which clamps the peak
motor voltage to a safe level for
standard motors. This option is used
when the distance between a single
motor and the drive is 600 feet or
less.
■
Output Line Reactor
This option provides an output line
reactor, reducing the DV/DT of the
AFD output voltage and lessening the
transmission line effect, to lower the
peak voltage at the motor terminals.
