N.O. contacts
Normally-open contacts. A pair of contacts on a relay that close when the
relay is energized.
open-loop system
A control system in which operations are carried out according to pro-
grammed instructions, but in which feedback is not provided for automatic
adjustments.
origin compensation
A parameter used to correct the origin from the position determined accord-
ing to the origin input signal.
origin proximity signal
A signal input to indicate when the position is near the origin to enable shift-
ing to a lower speed.
origin proximity
The region near the origin. When positioning enters this region, a proximity
switch may output a signal for deceleration.
origin
The point which is designated as 0 at any given time.
OUT refresh area
The first five of the ten IR words allocated to each Position Control Unit as
refresh areas.
output code
User-defined codes output following completion of a positioning action.
parameters
Data which determines limits and other conditions under which an operation
will be carried out. The Position Control Unit has both general parameters
and parameters specific to individual positioning actions.
pause (completion)
A positioning action completion code that creates a pause after reaching the
target position for the positioning action and then automatically begins the
next positioning action. The length of the pause is specified by the dwell time.
positioning action
The smallest increment of positioning possible. A positioning action is defined
by its completion code, dwell time, output code, speed number, and target
position. These actions are generally referred to by number and completion
code. For example, “#6, continuous” indicates positioning action #6 with a
continuous completion code.
present position
The numeric value in pulses defined as being the ‘location’ of the positioning
system at any one point in time. The present position is not absolute, but
rather can be defined or redefined as required by positioning operations.
proximity speed
A low speed at which positioning is executed near the origin.
pulse rate
The distance moved by an object driven by a motor divided by the number of
pulses required for that movement.
