Nidec Machine Tool Corporation will launch the MPLS series, an inductive coupling principle-type linear position detector that determines a machine’s position and detects its feed digitally, on November 1st. Intended for compact machine tools, it uses a signal-detection method and integrates numbers of substrates to realize a simple structure that does not require scale wiring or an analog/digital converter (A/D converter), and has a narrow width of 30 mm. By adopting an absolute (absolute mobility value-based) detection method, the MPLS series doesn’t require origin setting after inputting power. Furthermore, with the use of mounting hole locations and sizes that are the same as those of other companies’ products, it will be easy to switch to this product during the retrofitting or overhaul of a used machine.
The MPLS series is a high-performance scale capable of detecting a linear axis’s position, with a resolution of 0.05 μm and a pitch accuracy of 10 μm. The conventional series, MPLN, would install a scale and a head onto a machine to be measured, and use a control unit to transmit/receive electric signals from both sides. The new MPLS series uses a newly developed detection pattern to receive scale-generated signals without interference, eliminating the need for scale wiring.
Furthermore, with a longer measurement length, the MPLS series can widen its measurement range, or reduce its installation space. Moreover, the newly developed free user-assisting software can switch to output specifications that meet the type of a control unit, and fine-tune the matching between a machine and the location detector, to contribute to location detection under optimum conditions.
The inductive coupling principle method, the primary feature of Nidec Machine Tool’s MP scales, boasts an excellent durability that keeps the detection accuracy from being affected by contaminants, oil, and condensation.
The MPLS series will be unveiled and on display with the wide-type MPLW series that was launched this April, at the Japan International Machine Tool Fair (JIMTOF2022), scheduled to be held from November 08 – 13 at the Tokyo International Exhibition Center (Tokyo Big Sight).
