MOTION CONTROL
Refers to positioning control.
MOVEMENT AMOUNT PER PULSE
When using mm, inch, or angle units, the
movement amount is calculated and output
from the machine side showing how much the
motor shaft moves per pulse. Equivalent to the
positioning detection units. Positioning
accuracy in smaller units is not possible.
On the motor side, the movement amount per
axis rotation is normally designed as a
reference, so it is calculated as follows.
Movement amount per pulse =
P rate
No. of pulses per
encoder rotation
×
Movement amount
per rotation
Amount the motor moves (travel) per pulse.
MULTIPLICATION RATIO SETTING
This refers to the P rate.
Refer to the term "P RATE".
NC LANGUAGE (Numerical Control
Language)
This is the language punched into the paper
tape that instructs the machining to the NC
module.
The NC language consists of EIA codes (EIA
language), ISO codes (ISO standards), and
JIS codes (JIS standards).
NEAR-POINT DOG TYPE ZERO POINT
RETURN
During zero point return, the axis starts to
decelerate when the near-point dog turns ON.
When the axis has moved to near-point dog
OFF at the creep speed, the first zero point
signal position is set as the zero point address.
The length of the near-point dog is the point.
Refer to the term "ZERO POINT RETURN
METHOD".

NO-DWELL MOTION
At the start end and final end of the operation,
reciprocation is continued with the random
acceleration value with no dwelling. This
reduces the acceleration (A) value.
NOTCH FILTER
The notch frequency is set according to the
machine system's resonance frequency.

NUMERICAL CONTROLLER
Advanced positioning carried out using a
device called a numerical control module (NC
module). This control can be used to carry out
high-accuracy, high-speed control of 3 or more
axes. It is possible to control movement for
complex curved lines and curved surfaces.

ONE-DWELL MOTION, DWELL-RISE-
DWELL MOTION
If the start end or final end of the stroke is
stationary, and the same curve is returned for
the rising stroke or lowering stroke, this can be
used to reduce the acceleration and make the
movement smooth.
