APPENDIX 8 EXPLANATION OF TERMS
tool position to CNC. An absolute pulse coder is
supported by a battery.
PWE . . . . . . . . . . . . . . . . . . Abbreviation for Parameter Wriie Enable. Parameters
can be written.
Reference counter . . . . . . . .
Counter that creates a grid to be used by reference
position return.
Reference position . l . . . l . l
Specific point of an NC machine tool on a machine
coordinate system. Generic name for a machine
reference position, home position, initial position, or
tool position, etc.
Reset
. . . . . . . . . . . . . . . . . To return the numerical control unit to the initial
status.
Rewind
. . . . . . . . . . . . . . . .
To rewind a tape.
S function
..............
Sequence control
.........
Sequence number
Serial pulse coder , . . . . . . . .
Setting data (parameter)
Single block
.............
Skip function
............
Spindle orientation
Standard ladder program . . . .
Function that specifies the spindle speed.
Control that sequentially executes each control stage
in a pre-defined order.
Number that indicates the relative position of a block
in the program.
Pulse coder that can be used by the Power Mate B.
This pulse coder serially transfers such information
as the motor position to the CNC. It has a high
resolution.
Type of parameter. The contents of this data can be
modified on the parameter screen.
To execute only one block in the program.
Function that cancels the remaining travel and
advances the tool to the next step when an external
signal is sign during movement along an axis.
Function that stops the spindle at the predefined
angle.
A ladder program is usually created by a machine
tool builder. Power Mate has a built-in ladder
program. The range of usable signals and pin layout
of DVDO connectors, etc., are fixed. If the machine
tool can be controlled within these conditions,
however, a ladder program need not be created.
Step feed . . . . . . . . . . . . . .
To feed the tool by the pre-defined amount each time
a pushbutton is pressed.
Stroke check . . . . . . . . . . . .
To check whether the tool has exceeded the stroke
limit.
Subprogram . . . . . . . . . . . . .
Part of an NC program. The subprogram is called
and executed by an instruction from the main
program or another subprogram.
