WORD DEVICES
This is a device used in the PLC, and is an
element having data. One point is a device
configured of one word. Word devices include
the timer (T), counter (C) and various registers
(D, R, W, Z, V, A), etc.
X AXIS
Two-dimensional left/right horizontal direction.
XY TABLE
Device that can move the table in the X
(horizontal direction) and Y (vertical direction)
to simplify positioning work.
Used to drill holes in the plate, or to draw
figures.
X table
Y table
Ball screw
X table
Y axis servomotor
X axis servomotor
Base table
Y AXIS
Two-dimensional forward/backward direction.
Z AXIS
Three-dimensional up/down movement.
ZERO POINT
This is the reference position for positioning.
Positioning cannot start without a reference
point.
Zero point
This point is the reference.
ZERO POINT RETURN DATA
Data required by the motion controller to return
to the zero point. This value is determined by
the machine design, and requires the machine
design to be changed to change to value later.
This point is the reference for zero point
positioning, so if a power failure occurs during
positioning, or if the power is turned OFF and
the axis is moved manually, the current value
in the motion controller will deviate. In this
case, carry out zero point return. When zero
point return is started, it will search for the
near-point dog, regardless of the current value,
and will change to the creep speed.
ZERO POINT RETURN METHOD
The zero-point dog type, count type or data set
type can be used.
ZERO POINT RETURN REQUEST
This signal turns ON in the following cases
when using the increment method.
1) When the power is turned ON.
2) When the PLC READY signal turns OFF.
3) When the parameters or zero point return
data are written from the peripheral device.
4) When the following is selected during the
peripheral device's test mode
Zero point return
Positioning
JOG operation
Manual pulse generator
Whether to carry out zero point return in
these cases is up to the user.
ZERO POINT SIGNAL
1 pulse (or 2 pulses) generated per axis
rotation of the pulse generator.
This signal is used in the positioning zero point
return. Also called a Z phase, Z signal or PG0.
Refer to "PULSE GENERATOR".
Z PHASE
Also called PG zero.
Refer to the term "ZERO POINT SIGNAL".
