A - 47
G CODE
2-digit (00 to 99) coded to designate the NC
unit axis control function. Also called the G
function.
Example:
G01 Linear interpolation
G02 Circular interpolation CW (clockwise)
G04 Dwell
G28 Zero point return
G50 Maximum spindle rotation speed setting
GD2
Refer to the moment of inertia. Total sum of
the mass dm of each minute element
configuring an object, and the square of the
distance r from a set straight line.
The relation with GD2 is issued with 4gl using
the gravitational acceleration as g.
GEAR
A conveyance module used in the mechanism
program for the virtual mode, which branches
the main shaft rotation to the output module.
The gear ratio and rotation direction can be
set.
GRID
Reference horizontal lines and vertical lines
handy for laying out parts on the MECHANISM
EDIT screen.
HARMONIC MOTION
This is a type of cam curve.
With this movement, the displacement X can
be expressed with the following expression for
a right angle element in uniform speed circular
movement:
X = a°cos (ωt + Φ0)
Where, a is the vibration, ω is the amplitude,
(ωt + Φ0) is the phase angle and Φ0 is the
default phase angle
INCREMENTAL ENCODER
A device that simply outputs ON/OFF pulses
by the rotation of the axis. 1-phase types
output only A pulses, and do not indicate the
axis rotation direction. 2-phase types output
both A and B pulse trains, and can judge the
rotation direction. The direction is judged to be
forward if the B pulse train turns ON when A is
ON, and judged to be reverse if A turns ON
when B is ON. There is also another type of
incremental encoder with a zero point signal.
The most commonly used incremental
encoders output between 100 and 10,000
pulses per axis rotation. Refer to "ENCODER".

INCREMENTAL MODE
With this method, the stop point during
positioning is 0, and the position is indicated
with the designated direction and distance.
Also called the relative address system. This
system is used in fixed-dimension feed, etc.
Compare ABSOLUTE SYSTEM.

INERTIA
The property of an object, when not being
affected by external forces, where it tries to
maintain its current condition. The inertia
moment.
