Model 503
PRODUCT DESCRIPTION
Model 503 is a complete pwm
servoamplifier for applications using
DC brushless motors in torque
( current ) mode. It provides six-step
commutation of three-phase DC
brushless motors using 60° or 120°
Hall sensors on the motor, and
provides a full complement of features
for motor control. These include
remote inhibit/enable, directional
enable inputs for connection to limit
switches, and protection for both motor
and amplifier.
The /Enable input has selectable
active level ( +5V or gnd ) to interface
with most control cards.
/Pos and /Neg enable inputs use failsafe (ground to enable) logic.
Power delivery is four-quadrant for
bi-directional acceleration and
deceleration of motors.
Model 503 features 500W peak power
output in a compact package using
surface mount technology.
An internal header socket holds
components which configure the
various gain and current limit settings
to customize the 503 for different loads
and applications.
Separate peak and continuous current
limits allow high acceleration without
sacrificing protection against
continuous overloads. Peak current
time limit is settable to match amplifier
to motor thermal limits.
Header components permit
compensation over a wide range of
load inductances to maximize
bandwidth with different motors.
Package design places all connectors
along one edge for easy connection
and adjustment while minimizing
footprint inside enclosures.
High quality components and
conservative ratings insure long
service life and high reliability in
industrial installations.
A differential amplifier buffers the
reference voltage input to reject
common-mode noise resulting from
potential differences between
controller and amplifier grounds.
Output short circuits and heatplate
overtemperature cause the amplifier to
latch into shutdown. Grounding the
reset input will enable an auto-reset
from such conditions when this feature
is desired.
