applications to provide the widest selection of Dynapar brand
products for the industrial drive control market. These products
bring unprecedented ease of use, increased f exibility and
better performance into the mainstream of industrial control.
A full line of Dynapar brand encoders and accessories
complement the electronic controllers and allow one stop
shopping for complete motion control solutions.
MOTION CONTROL FUNCTIONS
Closed loop speed controls use an electronic controller and
a feedback device which is coupled to the system. By knowing
the desired speed and measuring the actual speed, the
controller can make adjustments continuously to provide better
accuracy, load regulation and isolation from power line
disturbances.
Master speed controls regulate a single motor or drive using
an operator adjustable setpoint. The speed is usually entered
numerically with a keyboard and display; some products also
include a means of remote adjustment. Other functions may
include the ability to start and stop at preprogrammed rates for
smooth acceleration and deceleration. Applications that are
ideal for closed loop speed control, such as extrusions pumps,
are typical of processes that depend upon speed to maintain
quality.
Speed follower controls are used to make one part of a
system track another. Conveyor applications might require the
takeaway line to go slightly faster than the feed line. Mixing
applications often use speed followers to maintain a balance of
materials even though the production rate of the system may
vary.

SPECIFYING A MOTION CONTROLLER
In choosing a master speed control, the primary consideration
is given to the accuracy needed. This is usually a price/
performance issue, with higher accuracy control costing more.
Accuracies can range from 0.1% to 0.01%. Better performance
will also enter into the feedback device selection, the drive/
motor combination and even the mechanical design of the
machinery. How the operator sets the speed is another
requirement; it may be a keyboard entry, a knob adjustment,
pushbuttons or a combination of these. The simplest products
offer a single setpoint and method of adjustment while more
complex products have multiple setpoints or means of
adjustment. Added functionality such as ramping and open loop
operation may be important.
For speed followers accuracy is also a factor in system
performance. If the follower is at least as accurate as the signal
it is following, performance will not be compromised. Our
motion control products include features which make them very
easy to setup and operate. Setpoints can be programmed in
meaningful units such as length or a percentage of the master
rate. Calibration for speed readout and ramp control are typical
of the attention paid to user interface details.
