When the offset presetter (OFH # 30094) is closed in the automatic mode, the CRT automati-
cally switches to the tool length/tool diameter measurement screen, placing the system in the
measurement mode.
When signal SPST #30097 from the touch sensor is closed in this state, the axis offset amount
is computed and written into memory.
20.2.36 WORK PRESETTER FUNCTION INPUT (WSS # 30090, WSH # 30091, WSC # 30092,
WSG # 30093)
(1) Function Overview
The work coordinate shift amount is automatically written into memory with the reference
manually brought into contact with the touch sensor.
(2) Measurement Types
The following four types of measurements are made.
Reference plane measurement
When the touch sensor is brought into contact with the X, Y, and Z reference planes, the
detected coordinate values are written as the work
coordinate shift amount data.
Reference hole measurement
When the touch sensor is brought into contact with three arbitrary reference hole points, the
reference hole center is written as the X- and Y- axis work coordinate shift amount data.
Reference groove measurement
The center of two points of the reference groove or the like is written as the work coordin-
ate shift amount data.
Coordinate rotation measurement
The work inclination is measured and written as the work coordinate shift amount data.
(3) Measurement Screen Operating Procedures
Reference Plane Measurement
Place the X, Y, and Z axes in the measurement start positions.
Enter the manual mode.
Turn ON work presetter (reference plane) signal WSS #30090.
Using the page (up/down) and cursor (up/down) keys, set a desired work coordinate
system (the page keys do not work for coordinate setup option A).
Touch sensor signal SPST # 30097 automatically recognizes the axis turned ON (axis
moved) and writes the current value (MACHINE POSITION) as the axis work coordinate
shift amount data. Reference plane measurement can be made of the X, Y, and Z axes.
When all necessary work coordinate systems are completely set up, turn OFF work
-presetter (reference plane) signal WSS # The display then switches to the work
coordinate system shift screen.
