APPENDICES
TURNTABLE
A rotating table, which is turned using power.
The table is used divided from one 360°
rotation into the required locations for work.
The positioning control unit is "degree".
Rotated by the motor
30°
UNIT SETTING
This is the setting of the unit for the actual
address to which positioning is required, or for
the movement amount.
The following units can be set: mm, inch,
degree and pulse. The initial value in the
parameters is a pulse unit.
WARNING
A warning is output as a warning code in when
an abnormality is detected that is not serious
enough to require cancellation or stoppage of
the positioning operation. Warnings are
handled differently than errors.
WINDOW
These are the selection menus that appear on
the screen when the QD75 is started.
• Menu selection window
•
Mode function selection window
•
Sub-function selection window
• Execution/setting selection window
WITH MODE
This is the mode that outputs the M code
before the start of the positioning. This mode
turns ON at the positioning start, enabling
voltage to be applied to the welding
electrodes, display of positioning speeds, etc.
Refer to the term "AFTER MODE".
XY TABLE
This is a device that moves a table in the X
(latitudinal) and Y (longitudinal) directions so
that positioning can be carried out easily.
There are also commercially available
products.

Z PHASE
Also called "PG zero". Refer to "ZERO
SIGNAL".
ZERO SIGNAL
This refers to PG0 of the pulse generator
(encoder) (one detection per shaft rotation). It
also called "Z phase". Refer to the term
"PULSE GENERATOR".
