Expanded： 100 µm, 50 µm, 25 µm, 20 µm, 2 µm, 0.05 µm, 1 degree can be added |
| Display resolution |
Measuring unit input resolution or higher and diameter display (except for angle display) |
| Input signal |
A/B quadrature signal, Z signal (Conforms to EIA-422) |
| Minimum input phase difference |
100 ns |
| Quantization error |
±1 count |
| Alarm display |
Measuring unit disconnected, Excess speed, Maximum display amount exceeded, Power failure, Error in stored data |
| Reset |
Resettable by key switch operation and external reset |
| Preset |
It is possible to store/call 3 kinds of numbers. |
| Reference point detection |
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) |
| Data storage |
The value displayed before the power was turned off and setting values are stored |
| Linear error compensation |
A fixed compensation is applied to the measuring unit’s count value. Compensation amount Standard: ±600 µm/m (Expanded: ±1000 µm/m) |
| Segmented error compensation |
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 µm (at each section) |
| Scaling |
Scaling factor：0.100000 ～ 9.999999 |
| Program |
- Machining coordinates can be programmed (number of program steps: 850 max.)
