Nidec Machine Tool Corporation offers the MPLS series, an inductive coupling principle-type linear position detector that determines a machine's position and detects its feed digitally.
This product, intended for compact machine tools, utilizes 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, and to have a narrow width of 30 mm. In addition, by adopting an absolute (absolute mobility value-based) detection method, the MPLS series does not require origin setting after inputting power, while being able to be connected to a control unit that the new series cannot be connected to with an incremental (relative mobility value-based) detection method.
The MPLS series is a high-performance scale capable of detecting a linear axis 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 latest series uses a newly developed detection pattern to receive scale-generated signals without interference, eliminating the need for scale wiring. In addition, the latest MPLS series, which has inside its head an A/D converter's function to convert a scale-generated electric signal into a digital one, needs to use only its scale and head to transmit/receive signals to/from a machine's control unit. These technological developments have eliminated the need of scale wiring and A/D converters, while the reduced number of required components and the shortened manufacturing process have achieved a low price and a short delivery lead time for the product.
Regarding installation compatibility with other companies' products, the MPLS series uses a product length and mounting hole intervals that are the same as those of other companies' products. 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, features enhanced durability that keeps the detection accuracy from being affected by trash, oil and condensation.
