Measuring unit input resolution or higher and diameter display (except for angle display)
A/B quadrature signal, Z signal (Conforms to EIA-422.)
Measuring unit disconnected, Excess speed, Maximum display amount exceeded,
Power failure, Error in stored data
Resettable by key switch or remote reset.
It is possible to store/call 3 kinds of numbers.
The reference point of the measuring unit can be detected, and the datum point
can be relocated (during connection of measuring unit with a reference point)
The value displayed before the power was turned off and setting values are stored
A fixed compensation is applied to the measuring unit's count value.
Compensation amount Standard: ±600 um/m (Expanded: ±1000 um/m)
The movement range of the measuring unit with a reference point can be divided into a
maximum of 32 sections, and error compensation is performed for each of these sections.
Compensation amount: ±600 um (at each section)
Scaling factor: 0.100000 to 9.999999
Machining coordinates can be programmed (number of program steps: 850 max.)
1. Manual programming by key switch
2. Automatic programming by playback
3. Mirror image during program execution
4. A canned cycle (bolt hole, line hole, simple R cutting) can be inserted in the program.
(LH71A only)
Can be displayed as an angle value when the Digiruler is pasted to the arc surface,
and the diameter and Digiruler resolution are entered
The display is turned off when no operations are made for a preset time.
