Abstract
Description
以下、本発明の実施の形態を図面と共に説明する。
電源エリア(1)は、装置電源21から電力供給を受けている電源エリアである。電源エリア(1)には、CNC CPU11、メモリコントローラ12、バッテリ16などが配置されており、装置電源21がオンになると該装置電源21から電力供給を受けて動作し、装置電源21がオフされると電力供給が停止され動作を停止する。また、装置電源21がオンになっている間、バッテリ16は該装置電源21から供給される電力により充電される。
このような構成を備えた数値制御装置1の動作について、以下でいくつかの動作状況に分けて説明する。
ワイヤレス給電機能およびワイヤレス通信機能を備えた外部機器2をワイヤレス給電兼通信用アンテナ32に近づけると(または、USBケーブルを用いて外部機器2をUSBコネクタ33に接続すると)、外部機器2からワイヤレス給電兼通信用アンテナ32経由での給電(または、USBコネクタ33経由での給電)が行われ、外部給電エリア(3)、およびバッテリ電源エリア(2)に電源が入り、外部給電エリア(3)、およびバッテリ電源エリア(2)内の各デバイスが動作可能となる。
NAND FLASH14やバックアップSRAM15等の不揮発性メモリについて、予め数値制御装置1の設計・評価時に、時間経過とともにデータエラーが増加する傾向を測定し、近似の関数データとして装置のプログラムに組み込んでおく。
