Brushless servo drives, amplifier/motor

LX Amplifiers can be easily adjusted to operate with a variety of motors and controllers.
A personality module attached to the amplifier retains all adjustments. If an amplifier
needs to be replaced, the personality module can be removed and attached to a new
amplifier, thus alleviating the re-adjustment process.
Troubleshooting is aided through the use of status LEDs located on the front panel of
the amplifiers. The LEDs continually keep the operator informed of the status of the
amplifier at all times. In addition to the LED indications, fault conditions such as resolver
fault and motor over temperature are announced as a contact signal output which can
be monitored by a host controller.
Input power voltage can range from 96 to 264 VAC 50/60 Hz without jumper or switch
selection. A 230 VAC 50/60 Hz, 3Ø supply will deliver the maximum output power.
Optimum performance from a servo system is accomplished by carefully matching the
motor and amplifier. Emerson EMC's DX Series of servo motors has been engineered
to compliment the LX servo amplifier, providing unparalleled reliability and performance.
The DX Motors are available in a number of configurations including connectorized or
waterproof (IP65) versions. Most motors are also available with a mechanical holding
brake.
NEMA motor face dimensions are available in addition to the metric dimensions on four
motor models to greatly simplify mounting to many standard reducers.
DXE-208 NEMA 23 compatible
DXE-316 NEMA 34 compatible
DXE-455 NEMA 56C
DXE-490 NEMA 143TC
DXE-4120 NEMA 143TC
The signal and power connections are conveniently located on the drive front panel to
simplify wiring in multi-axis applications.
