LH71A / LH72
(E) 2-1
Display Resolution Switching
The display resolution can be selected from the following.
Linear: 0.1 µm – 10 µm and diameter display
Angles: 1 second – 10 minutes
(Choose the appropriate setting for the direct measuring unit.)
(You can add other types of display resolutions. See page 5-2.)
Machine Error Compensation
The LH71A/LH72 compensates errors arising from the inclination or deflection of a machine tool, and
displays the actual displacement of the machine. Thus, the displayed value accords with the actual displacement
of a workpiece to achieve high-accuracy positioning and machining and restoration of machine tool accuracy.
(Linear compensation, Segmented error compensation)
Data Storage
Data on display and preset data are held automatically.
Therefore, data is retained even after power is turned off or in case of a temporary power outage.
Preset
Each axis can have up to three preset values.
This is useful when setting multiple preset values.
Measuring Unit Reference Point Detection
Combining with a measuring unit with a reference point makes it possible to detect the measuring unit
reference point at all times.
This can be used as the reference point for machining.
You can also freely set the amount of reference point offset and easily restore it, which makes reference
point setting on a boring machine and the like very effective.
Program
– Write Program mode –
• This lets you manually enter a program in the Edit mode.
• Playback program: The program is created with the content of actual machining.
– Run Program mode –
• Machining procedures are displayed for each stage.
• The Mirror Image function flips the data polarity for each axis.
Multi Datum Point
You can save settings for a number of preset ABS coordinate datum points (150).
Digiruler Easy Angle Display
You can easily display the angle by pasting the Digiruler on an arc.
Scaling
The counter can count the actual moving distance on an enlarged or reduced scale using any multiplier
within the setting range. This can compensate for shrinkage of resin, etc. when making dies, or convert
product dimensions to die dimensions.
